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
