    ANSYS Workbench "New Environment" Toolbar

    I am trying to learn Ansys Workbench to do SV simulation. One step is to create environment. But when I tried to expand "Model" to insert "New Environment," I could not find it in the drop down menu. The menu only lists Virtual Topology, Symmetry, Coordination Systems. Does anyone encounter...

    MPPLOT two data sets

    Anyone knows how to use plot two data sets (such as EX, ALPX) in one graph? I tried MPPLOT, it seems that it only allows to plot one property. Thanks for your help!

    stress re-scale

    I performed some stress analysis on the mechanical structure using ansys and obtained the stress distribution. how can I change the stress bar scales so the details of the low stress area can be shown in the graph? Thank you for help.

    map meshing

    Any advise on how to map mesh circular shapes, such as a cylinder, or ball? CYLIND, 0.016/2, 0, 0.022/2, 0.025/2, 0, 360 Any written macros published on the web? Thank you very much.

    ENTH?

    When I input material proerpty as a function of temp. in ANSYS, I encountered the following message: Phase change by coincident temperature has been removed, use ENTH property instead, the MPTEMP command is ignored. What is ENTH? I could not find it in the search database...

    commands for cross sectioning

    I have one more question, I used following commands to see a cross section: /VIEW, WPLANE, /CPLANE, 1 /TYPE, , 5 but this applies to the deformed shape, all the coordicate values has been changed. For example, I want to see the stress distribution on a flat surface, but the surface has become...

    commands for cross sectioning

    I just figured out, use /TYPE, , 5. Thank you.

    commands for cross sectioning

    Thanks. I used the following commands to do xection. /VIEW, 1, base/2, -base/2, 0 WPLANE, 1, 0, 0, 0, dieL/2, dieL/2, 0, 0, 0, baseT /CPLANE, 1 /TYPE, , 1 But this only shows one thin slice (wplane). Is there any way to show the part of the object behind the section plane?

    commands for cross sectioning

    I built a relatively complex model and was able to run it. I would like to check the stress distribution inside the object. may you advice how to do cross sectioning. what are the commands? thank you.

    ANSYS close down itself

    I am trying to run ANSYS using macros. after building the model and applying the loads/constrains, I run ANSYS using code SOLVE FINISH /POST1, PLNSOL, S, EQV PLDISP, 2 /DSCALE, 1, 0 /EOF ANSYS automatically closes down without error message. Do you know what could be the...

    Instable results if not using VGLUE

    I am trying to simulate an object with several component stacking together. The edge of the bottom component is fixed (displacement =0). The pressure is applied on the top component. Initially I glued them together and I got good results. However, if I do not use the VGLUE command to simulate...

    Cross sectioning view of an object

    I did stress analysis on an object with several components stacking up. I'd like to see the stress distribution within the object along the diagonal. what commands should I use to create this cross sectioning view? Thank you!

    training class: introduction to Ansys Part II

    I plan to attend a training class on Ansys Part II, but I am not sure what I can get from the class. anyone attended this type of classes? any advice? any better classes? I wish through this class I can build complicated geometries using macro, perform map meshing, extract parameters from global...

    solid model volume numbering

    I created two volumes by using the V commend. then I'd like to substrate one from the other by using the VSBV command. This needs the volume numbers. Please advise how to number the volumes, what is the command? Thank you.

    Ansys traning and macro

    Any Ansys training class to simulate solder joint reliability? Can anyone point me to the Macro to build the Ball Grid Array package model and map meshing? Thank you so much!
