    You can do this easily with freeware, see the attached video that uses a free ware called pdf creator. (rename the video attached as jpg below to wmv)

    The video is only for demonstration, please check with pdf creator about its licensing and use. we cannot be responsible for external software and its effects. http://www.pdfforge.org/pdfcreator

    If you make the pdfcreator for example the default printer, then you can use the keyboard shortcut of ctrl + f3 or ctrl + f1 to print from HyperView.

     


    Note while saving you can choose the file format type to .eps, not doing so will save in the default pdf format.

    best to import into HyperMesh, select the elements and organize into separate components, 

     

    You could create sets in HyperView for selected elements and change the colour of the sets if necessary to do it in hyperView itself.

  6. herbertvwright liked a post in a topic by Rahul Ponginan in Why will the Student edition 12.0 not run on a 32 bit machine?   
    The Student Edition 12.0 is designed for 64 bit Operating System (windows specifically)

    64-bit refers to the size of the address space. When you compile a 32-bit program, the code is turned into assembly language and each instruction has an address that is 32-bits long in memory. Conversely a 64-bit program uses a 64-bit address. The real advantage is that any given program can access a lot more memory in a 64-bit system.

    Also, 64-bit processors are instruction set compatible with 32-bit (on the same instruction set). That is, a 64-bit processor should have no issue running a 32-bit program. In the case of IA-32 and x86_64, this is handled by a library in the OS that truncates the memory addresses in a predictable way.

    The reason you can’t run 64-bit program on a 32-bit OS (even on 64-bit hardware) is because the OS is only concerned with half the memory address, and it gets instructions that don’t make sense to it.

  10. Nic liked a post in a topic by Rahul Ponginan in How can I apply multiple constraints or loads in a subcase?   
    OptiStruct can only accept one SPC and one LOAD component in a subcase, by default. In other words, multiple load collectors with e.g. different SPC's can't be referenced in the load step panel. There are two ways to apply multiple constraints and loads in a subcase.

    1. Put multiple loads in one load collector, and include that one load collector in the subcase. The same method can be used in the case of multiple constraints.

    2. Create load collectors for each and every load and constraint set. When you want to apply multiple loads in a subcase, a new load collector needs to be created with the LOAD card (=CardImage=Load). Then, individual load collectors can be combined using the LOAD card. The LOAD card also enables you to associate an independent weighting factor to an individual load collector. In the case of applying multiple constraints, create a new load collector with the SPCADD card (=CardImage), and follow the same procedure as in the multiple load case. Once the combined load collectors are created, they can be applied in a subcase.

    Answer:
    1) Please create the mass element through the 1D --> Masses Panel (Mesh --> Create --> Masses, if you want to access the panel via pulldown menu).
    2) Afterwards, go to the "Card Edit" Menu that you will find within the toolbar --> see the attached screenshot
    3) Select all the elements that you want to edit. If you select multiple elements, please choose also the correct type and card image (mass and CONM2) --> hit the edit button
    4) Select the continuation line and enter the moments of inertia for your selected elements

  13. Hyperman liked a post in a topic by Rahul Ponginan in FAQ 19. How to coarsen your 2d mesh?   
    Go to Mesh menu > create > coarsen mesh

    Use the Coarsen Mesh utility to simplify the mesh by combining many small elements into a smaller number of larger ones

    This dialog allows you to pick the Components that you wish to simplify, any Hard points (such as those defining a hole or ridge) that must be preserved, a new Element size, and a Mesh type (Mixed or Trias-only). In both cases, you must click the selector twice, as if you were accessing its extended entity selection menu; however, the second click opens a temporary panel in the panel area. This panel allows you to select the desired components or nodes, and then proceed in order to close the panel and return to the Coarsen Mesh dialog.
    Once you set the desired options, you can Mesh the selected components. If the results are not satisfactory, you can Reject the new coarse mesh, change the options, and try again.
    Manually
    Detach elements from its neighbouring mesh and remesh the selection <can be a bad idea if a good connectivity is required or the number of elements is too large>
    Create surface from elements, delete the selected elements and remesh the surface, which has points on its edges created from the surrounding mesh. Based on the difference of old and new mesh sizes, can provide a very good connectivity

    HI, 
     
    We see that you have ordered the Altair student edition and this was delivered to you,
     
    The software requires a license file to function, You should find the license file attached to the email
     
    After downloading the license file, rename it to altair_lic.dat and place the same in the <installation directory>/security folder
     

     
    If you have set an environment variable, then the older license will be used, make sure the variable points to the new license file in that case, it is suggested you remove any Altair variable if you have set it, If you have already done the above and still face the error, let us know and we will troubleshoot accordingly.

    That is correct, Simlab is not part of the student edition currently,
  25. Mrt liked a post in a topic by Rahul Ponginan in Linear and Non linear analysis, iteration, increment, step etc explanation   
    The equation of motion for a static analysis is as below:
    [K] {X} = {F} ------------------------------------------ (1)
    [K] --> Global Stiffness Matrix
    {X} --> Unknown Displacement
    {F} ---> External Force Applied.
    For the body to be in static equilibrium, the net force acting at every node must be zero. Therefore, the basic statement of static equilibrium is that the internal forces, I, and the external forces, F, must balance each other:
    [K] {X} is nothing but internal force 'I'
    Equation (1) now becomes,
    ==> I = F or I - F = 0 -----------------------------------(2)
    In Dynamic Analysis, the imbalance between the external and internal forces results in an acceleration:
    F - I = M a.
    F --> External Forces
    I ---> Internal Force
    M*a --> Inertial Forces (mass times acceleration)
    In linear static analysis the stiffness matrix is constant and shall not change/update throughout the analysis. There are many check need to be performed once you have linear static results for well conditioned problems.
    The equation (1) is decomposed one time to find the unknown displacement.
    [K] {X} ={F}
    After decomposition, a singularity may lead to an incorrect solution. In static analysis to obtain {X} (displacements). Using these displacements, One can calculate a “residual” loading vector as follows:
    [K] {X} -{F} =δ F
    This residual vector should theoretically be null (equation 2) but may not be null due to numeric roundoff.
    In Nonlinear static analysis, The stiffness matrix changes in each and every iteration since the stiffness matrix is dependent on the external load. The external load in Nonlinear static analysis is applied in increments and time here has no physical meaning.
    Time is just a convenient way to apply full load in nonlinear static analysis. In Optistruct the incremental load is controlled by 'NINC' field in the NLPARM card for NLSTAT load steps, this is a fixed load increment method.
    If you add the PARAM,EXPERTNL,YES to the deck, the time increment method becomes automatic in which case, the increment (load) is increased or cut back based on the convergence rate.
    NLGEOM loadstep has automatic time step by default. In NLGEOM loadstep the RAMP load curve can be defined using TABLED1 card and then refer this in NLOAD1 card.
    In nonlinear static analysis, OptiStruct uses the Newton-Raphson method to obtain solutions for nonlinear problems to maintain the residuals close to zero (equation 2)
    In a nonlinear analysis the solution usually cannot be calculated by solving a single system of equations, as would be done in a linear problem. Instead, the solution is found by applying the specified loads gradually and incrementally working toward the final solution. Therefore, OptiStruct breaks the simulation into a number of load increments (NINC) and finds the approximate equilibrium configuration at the end of each load increment.
    It is important that you clearly understand the difference between an analysis step (NLSTAT / NLGEOM), a load increment (NINC of NLPARM card), and an iteration (MAXITER of NLPARM card)
    The load history for a simulation consists of one or more steps. Within a step you will have many no of increments (NINC), within increment there can be many no. of iteration (MAXITER). OptiStruct checks the equilibrium equation ( equation 2) for each and every iteration. If the solution from an iteration is not converged, OptiStruct performs another iteration to try to bring the internal and external forces into balance.
    An increment is part of a step. An iteration is an attempt at finding an equilibrium solution in an increment when solving with an implicit method. If the model is not in equilibrium at the end of the iteration, OptiStruct tries another iteration. With every iteration the solution OptiStruct obtains should be closer to equilibrium; sometimes OptiStruct may need many iterations to obtain an equilibrium solution. When an equilibrium solution has been obtained, the increment is complete.
