    From tcl 8.5, use {*} instead of eval *createplane 1 0 1 0 {*}$node_coords or eval *createplane 1 0 1 0 $node_coords

    Try this code: *createmarkpanel elems 1 "Select Elem" foreach { x_min y_min z_min x_max y_max z_max } [hm_getboundingbox elems 1 0 0 0] {} puts "X= ( $x_min , $x_max )" puts "Y= ( $y_min , $y_max )" puts "Z= ( $z_min , $z_max )"

    Hi, You are right, I use a commercial version. I create a python script to reproduce all the modifications that I done in the initial project (project that you send us). To run the python script: Open the initial project (project you send) Load the python script (project >> command file: run a python file, select the script python). Best regards. Flux_2018.zip

    Another way: create a rigidlink or mass elements on temp nodes and then do equivalence

    Hi, According to the picture that you send me, I made modifications on your Flux project (see attached file). IN your project: You splited the magnets in 4 parts (In the picture three are two poles and not four poles). I add the frame (stator) as in the picture You need to check the dimension of the new model In the circuit, all the elements are not connected. I create a new circuit according to the picture that you end us I made a connection between the circuit and the face region. I changed the orientation of the magnets I create anew face regions (stator and rotor air) If you want to create the circuit, you can use the context circuit in Flux (physics >> circuit: circuit editor context). You will find attached your Flux project ready to solve. Before solving the project, you need to check: The dimension of the device (according to the modifications) The value of the: Phase resistance Voltage source Inductance Resistance The characteristic of each brush segment Hope this will help. Best regards. new2_mod.FLU.zip

    Hi, The crushing behavior of the foam cells is represented by a stress plateau with irreversible strains. An elasto plastic behavior is introduced in the deviatoric part of the stress tensor in order to represent this phenomenon. σ dev plas = A + B (1 + C * γvol) with γvol = (V / V0) − 1 where σ dev plas is the plastic stress applied to the principal stress of the deviatoric tensor, γvol is the volume strain and A, B and C are modeling parameters. The densification phenomenon is modeled by a pressure term in the spherical stress tensor. σ spher ij = −P * δij with P = (− P0 * γvol) / (1 + γvol − Φ) where δij is the Kronecker symbol, Φ is the foam porosity and P0 the initial air pressure.

    Hypermesh is Open system (yes! that why I love it). All you need is to write a customized FE output template for your output. Have a look at the online help on this point.

    from the release notes, gmsh supports importing on Nastrand bdf file, since 2007. You can just export in Nastran template and import it in GMSH. 2.0.0 (Feb 5, 2007): new geometry and mesh databases, with support for STEP and IGES import via OpenCASCADE; complete rewrite of geometry and mesh drawing code; complete rewrite of mesh I/O layer (with new native binary MSH format and support for import/export of I-deas UNV, Nastran BDF, STL, Medit MESH and VRML 1.0 files); added support for incomplete second order elements; new 2D and 3D meshing algorithms; improved integration of Netgen and TetGen algorithms; removed anisotropic meshing algorithm (as well as attractors); removed explicit region number specification in extrusions; option changes in the graphical interface are now applied instantaneously; added support for offscreen rendering using OSMesa; added support for SVG output; added string labels for Physical entities; lots of other improvements all over the place.

    Hi Vishrut, Probably the road reference marker is to high compared with the tire marker. Try to lower in Z the road reference marker a bit, 10, 20mm should work. Best regards, Felipe.

    Hi granzer, This actually only means that the alignment of the connections between the elements is as smooth as possible in relation to the edge geometry. Left side has a lot better mesh flow, as the right side mesh. This is very important in crash (my field) and non-linear analysis. In general the mesh quality is improved by mesh flow (except number of trias). Best Regards, Mario

    this is only "visual", and there's nothing wrong with this. The most important thing is to guarantee that your beam elemets are correctly connected. Using a 1D model is that what you get always. If you are really interested in detailed stresses and joint stiffness, you should be using a 2D or 3D model for this, depending on your section type.

    Another option would be not to model the air above at all, just assume some convective heat transfer using a convective heat transfer coefficient with a corresponding reference temperature on the external surfaces of the oil/housing/transformer.

    Keep in mind that the good principle of forum is "sharing": when you post your question here, I can answer also here and another person who has the same "issue" as you can learn from it directly.

    Yes this is definitely possible with AcuSolve. Adding a multiphase approach would increase the run time and also force you to run transient. The easiest "trick" would be to also model the air volume in CAD and then define a new "solid" material with properties of air. This "solid" air will take into account heat transfer between oil and air. You could also run steady state with this approach.

    Hi Paulo, You can use "Total Shinkage Voume" result in Solidifcation. This is the combination of Porosity and PipeShinkage. The unit is volume already.

    The simple way is asking user to choice one element and you get element type from this selected element. So user has selected element type indirectly, via element. *createmarkpanel elems 1 "Select Element" set eList [hm_getmark elems 1] hm_markclear elems 1 set eid [lindex $eList 0] # we work only with the 1st element set typename [hm_getvalue elems id=$eid dataname=typename] puts "Element type= $typename" # Do something with selected typename

    I don't think there are such type of set. If you work from Tcl script, you can keep your lines, surfaces, points ID in LIST variable. Here's an example: set myLines [list 1 2 3] set myPoints [list 10 11 12] set mySurfaces [list 30 31 32] # Mesure shortest distance from surface 30 to set of lines *createmark surfs 1 [lindex $mySurfaces 0] *createmark lines 1 $myLines hm_measureshortestdistance surfs 1 0 lines 1 0 5

    Keep contact here if you want some help. If it's possible I would like to have a look at your model HM where your customer requests "all Hexa"? Another point, Hexa mesh is in general a good meshing technique which gives you, in general, the good analysis results. But this depends to the analysis goal and the Geometry. Mathematically, Hexa meshing is not always possible with any geometry. From point of view of FEA, don't fear TET meshing! A good TET mesh could give you better results than a "bad" HEXA one. Splitting TET element to get HEX elements is not so good technique to have good HEXA elements.

    It's not possible. When you split, 2 should be become 2x2=4 right? Do you use split mesh for Mechanical computation or CFD?

    Hello - I believe you have set up your Activate model, added the MotionSolveSignals block and connected it to other part of the Activate model. You might have to check the Path Preferences from where Activate gets information on which version of MotionView and MotionSolve needs to be used. In Activate - Use the File menu -> Preferences > Path Set the MotionView path to the ~hw_install/hwdesktop/hw/bin/win64 (I am presuming you are using Windows) Set the MotionSolve path to ~hw_install/hwsolvers/motionsolve/bin/win64 Set the MotionSolve license path ~hw_install/hwsolvers/common/bin/win64 The Python path is optional in case the MotionSolve model uses any python user defined subroutines.

    Hi Prajwin, SimSolid is not a part of Altair Student Edition. HyperWorks 2019.X learning course is available still in the learning section. See the image below. We are preparing the examination of the same and will soon be released. It is in the final stage. SimLab learning course is available and we are yet to release a certification exam (i do not know the release date).

    Hi, In the case of RBE2 elements, one node serves as the Independent and the other(s) the Dependant node(s). The Dependant node(s) simply follow the motion of the Independent node in the Degrees of Freedom that have been linked. These elements are useful to simply represent welds or to tie together two dissimilar meshes. One word of caution though is that RBE2 elements, as they rigidly link nodes together, can induce a stiffness to the model that may not be desired. RBE3 elements, on the other hand, serve to distribute loads without inducing unwanted stiffness. It is not an element to be used to model a connection, but rather an element to induce a motion in a node as a function of the weighted average of other nodes.

    you need to use HyperView for that: Load your results, and then>>Export Solver Deck. It will wexport the deformed shape, 1 to 1
