Thanks everyone. I just needed to back out the "equivalent modulus" of a composite panel by looking at the displacement for a certain load value. This is for a case study. Again, thanks for your replies.

Hi Can anyone share a 4 point bending test FEA model of steel beam or any other specimen? My specimen size is 24x3x0.382". Thanks Modeldamper

Hi RCatania I read one of your other posts regarding the use of femeshbetween and it worked well. Thanks for supporting.

Hi RCatania Thanks for your inputs. I will work on it. It has been helpful.

Hi I am new to API in FEMAP and I am trying to create a quad element from 4 nodes in API. I know how to create a surface and create the elements from the surface. But, I am wondering if I can create the element directly using the nodes. Thanks

All, I would like to know how to build a FEA model in Excel and import it into FEMAP. This is more like automation so that non-FEA person can simply change the material properties or change the thickness, to do some parametric studies. Is there any process that you would like to share? Thanks...

All I need help in getting the value of modal effective mass for mode 5 in .f06 file. Do I need to add the values in all degrees of freedom to get the value? MODAL EFFECTIVE MASS MODE FREQUENCY T1...

Hi Everyone, I am running random response analysis in NX nastran and i have a question. Can you let me know if the acceleration that i get is acceleration^2 or acceleration^2/Hz or just acceleration from the following command? ACCELERATION(SORT1,PUNCH,RPUNCH,NORPRINT,PHASE,PSDF) = 1 Thanks...

All Has anyone had experience in how to model a tuned mass damper in FEMAP or in general? Thanks a lot. Modeldamper

Thanks JBrackin. I will look into it and post questions if I have any doubt.

Hi I received two external superelement in *.op4 format with *.asm and *.pch files included, and I have to perfom a Nastran modal analysis can someone explain how to and where to attach the .asm and .pch files in the main file. I don't want the include command line for .asm and .pch files. I...

Thanks. I will look into it

Hi forum Can someone give information on vendors who can measure the 3D anisotropic properties (G11, G22, G33, G44, G55, G66 in Mat9 material card) of honeycomb core and what standards they use to measure these properties? Thanks

Thanks SW. I will look into it.

Hi I am looking for 3D orthotropic or 3D Anisotropic properties for the honeycomb core F40 3.1 pcf Flexcore (5052 AL) Does anyone have these properties? It will be of much helpful. Thanks

Hi I have a frequency dependent material property for a visco elastic material and I run the Direct FRF solution. When I estimate the damping loss factor using X-modal software (by converting the FE output .pch file to .UFF file to import in X-modal), I get a value (say 0.1). But when I use the...

Hi everyone. It will be nice if you could help me out in copying elements from one coordinate system to another coordinate system in FEMAP. Thanks

Hi This is how you should use it. You can give only one frequency dependent material. Can't use for multiple frequency dependent visco elastic material. Make sure that you don't enter GE values in other material cards ACCELERATION(SORT1,PUNCH,REAL) = 1 SDAMPING = 9 . . . $This is the visco...

Hi Chin. Sorry, I couldn't get back to you. Here is the .dat file. Top layer and the bottom layer are set at 250F and their nodes are 1,2,3,4,205,206,207,208. Rest of the nodes (middle layers) are set at 70F. Specific heat for material varies and I have assumed 80000 here. Hope this helps...

Hello all I need some help in thermal analysis in FEMAP/NX-Nastran. I have 17 layers stacked on each other. Initial temperature at the bottom and top of the layer is set at 250F. I would like to know the temperature of each layer as time goes on. How do I do that? Total time duration is 2hrs...
