    visualize failed elements in PATRAN

    Dear all, my .f06 file contains the element and plies that have failed using the TSAI WU criterion. However my model has more than 3000 elements. How can I import those results containing the failed elements so I can group them and viwe them? Cheers hyperen

    failure indices for Tsai Wu criterion

    Dear all, I want to find the failure indices using the Tsai-Wu criterion. I found out that with my version of Patran that is not supported(I have 2000.0 version). However I found in the Solutions Web site of Patrans technical support, a DMAP ALTERS that computes the indices. However, I put the...

    stiffness optimization

    Dear all, I have a rather large model, in which I apply a force , and I get a maximum displacement. Any suggestions on how I can calculate the stiffness of my FE model, so I can do a stiffness optimization? Any help? hyperen

    gravity load using concetrated mass

    cheers bjpil, the answers seem to be different therefore by applying an inertial load of g=-1, the concetrated masses must be taken under consideration in the solution

    boundary condition on an MPC

    Dear all, Is it wrong to apply a fixed boundary condition on a node that belongs to an MPC? Will it produce fatal errors? cheers hyperen

    concetrated masses 2

    By applying only a concetrated mass does this result automatically in application of a force at a single point? I inserted the mass property for the conm2 element from the property set card. But when I view the results and the reaction forces, it seems that the solution doesn't consider the...

    gravity load using concetrated mass

    cheers BJP, true , may be I do not need gravity. But applying only a concetrated mass does this result in application of a force at a single point? I inserted the mass property for the conm2 element from the property set card. But when I view the results and the reaction forces, it seems that...

    gravity load using concetrated mass

    hi all I want to simulate the weight of a structure using concetrated mass at certain points of the mesh. However I am not so sure whether by applying inertial load over the entire model, by this way nastran takes under consideration the weight at those points. The procedure I used was teh...

    user fatal message 2101

    hi all, I am hyperen and I am new in PATRAN/NASTRAN. I am running a simple linear analysis, on a not so simple winglet! However I get the following fatal message and so no .op2 file is written: *** USER FATAL MESSAGE 2101 (GP4) GRID POINT 1000905 COMPONENT 1 ILLEGALLY DEFINED IN SETS...
