  1. Hi,

    I have a .csv file with nodes coordinates and forces (x,y,z,Fx,Fy,Fz) that I need to import in HM. I found 2 solutions:

    • Use Field > realize
    • BCs > Create > Forces > Linear Interpolation

    Both take the .csv file as an input and apply its forces to the model.

    What are the differences? What should I use?

    Thanks for the help!

     


  2. Hi,

    I need to resolve a transient(direct) analysis on my model.

    There are 8 different imported load that I merged into 1 with a LOADADD card, then I create a TABLED1. Now  I need to create a TLOAD1 to give the forces a time dependence function. the problem is that TLOAD1 field "EXCITEID cannot reference the LOAD and LOADADD Bulk Data Entries". How can I resolve a transient analysis having more than 1 load?

    Thanks for the help!


  3. Hi,

    I need to use an external python package (openpyxl) to connect FLUX with a data sheet. I installed that package in the FLUX's "lib" folder but when i try to import it in the command prompt zone, an error showing "no module named openpyxl found" appears.

    How can i install external python package in the correct way?

    Grazie!


  4. for recapitulate:

    • I create an empty Load Collector let's say with ID 33. so SID = 33
    • Form X1 Y1 Z1 point coordinate from my file, i create a GRID point
      • in bulk file: GRID   ID  CP    X1    Y1   Z1
      • example:   GRID   123   0   1.2   3.4   5.6
    • I take that grid point ID, A1x A1y A1z (components of acceleration) from my file and i create the accel1
      • in bulk file: ACCEL1   SID   CID   A   A1x   A1y   A1z    ID
      • example:   ACCEL1     33     0      1   1E5   2E6    3E7   123
    • Itereate this for all 'N' acceleration that i have.

    Using this method i will end up whit my accelerations associated with nodes of the model. For the analysis i will use the load collector SID 33 as LOAD input.

    Am I right?

     


  5. Hi @Toan Nguyen, and thanks for your reply!

     

    The option that you suggest allows you to associate an acceleration to a node, but i have different acceleration for every node, tought, with this method, i have to import accelerations one by one and next find a way for associate the imported accels1 nodes to my model nodes.

    With forces it's possible upload a file like the one above, and HM automaticly import and map the forces. I'm searching something like this.

  6. Hi!

    I have an external text file containing: points of application x,y,z cordinates and relative x,y,z components of an accelaration that vary for each node. Something like this:

     

    X1   Y1   Z1   A1x   A1y   A1z

    X2   Y2   Z2   A2x   A2y   A2z

    ....

    Xn   Yn   Zn   Anx   Any   Anz

     

    I need to import this values in hypermesh for a dinamic analysis.

    If they are forces i can directly import that file, and mapping the acceleration point on the nearest model node. But whit accels this in not possible.

    How can i import the file and associate the acceleration at the model nodes for running the analysis in Optistruct?


  7. Hi,

    I'm trying to import a file from FLUX software, I export the geometry from FLUX in .IGES and .STEP. In both extension the imported geometry in hypermesh is uncomplete, some solids there are, other no. some lines are ok, other are free lines with no connection. I found a lot of problem in rebuilt the geometry with no succes.

    How can i fix this problem? is there someone how can works with both programs with no problems? 

    Grazie!


  8. Hi,

    There is a way to solve only a defined values of parameter and skip the ones that you don't are interested in?

    For example I have a grid that goes to 1by1 to 10by10 defined by two parameters: number of raw and number of culomn. I wanna compute only cetain combimation, lets say 3x4, 6x2, 2x6. How can i do it?

    Because if I create a solving scenario I can only put range of values, in this example i put number of raw from 2 to 6 an column to 3 to 6, in the computation FLUX will calculate the 5x2,5x3,4x3,2x5,2x4 exc.. several values that are not useful for me, Its a lot waste of time!

    thanks a lot!


  9. Hi

    Probably you lauch a solving too much complex and FLUX is asking you to increase the memory for meet the high request of hardware resorurces.

    For fixed it you have too option:

    -Change the memory dedicated to FLUX. For doing this go to Flux first page when you open it, in the bottom left corner there is the Option button, click on it and in the memory menu, move the cursor to increase the memory used

    -Use a larger mesh in your model, so the memory request will be less


  10. clink on View > Full Device. Flux will show you the full model, building (only visually) the periodicity and the symmetry defined.

    In your case will appear  "Unable to rebuild device because symmetries/periodicities create an infinite geometry" because, for the periodiciy, FLUX replicate every L_STAT/2 your model, with no limitation of the number of replication, the device is infinite
