I'm performing a thermal analysis with elements Tet4, and I was wondering if it is possible to obtain the value of the nodal volumes that are associated to each node in my model as an output
Setting aside the argumentation of whether it is meaningful at all to run a linear buckling analysis for multiple load cases, how to correctly model it?
In the case of a buckling analysis with only one subcase the analysis run without any issue…
Any documentation available for Linear Gap Sol 101? In particular looking for elaboration of this warning message in the .f06 file
*** USER WARNING MESSAGE 9095 (SUBDMAP CSTRDISP)
A DUPLICATE SHUT VECTOR HAS BEEN FOUND, USE RANDOM VECTOR
Hi everyone.
I am running a SOL101 with glued contact. Is it possible to get the forces/stresses between the glued part? Or because there are glued the forces and stresses are not possible to postprocess?
Thanks in advance
Has anyone document a workflow to implement Hot Spot Stress Approach of welded structures according to IIW Hobbacher (Ed), 2009?
I have encountered a scenario that the extrapolated stress at 0.4t and 1.0t is trending downwards instead of upwards.
I have sine and random analysis stresses I need to validate for our instrument models containing plate, solid and beam elements. To date, I have used the RMS stress components to approximate the RMS Von Mises for random or peak stress in sine.
How should I prescribe a rotation of a group of nodes about the y-axis of a CORD2R. Using SPCD seems to rotate about the globaly y-axis, not a local axis. Thank you
f06ファイル内の「O U T P U T F R O M G R I D P O I N T W E I G H T G E N E R A T O R」で出力される「 I(S)」の 慣性乗積「Ixy、Iyz、Izx」の定義を教えてください。
「Ixy = -Σmyx」 or 「Ixy = Σmyx」
「Iyz = -Σmzy」 or 「Ixy = Σmzy」
「Izx = -Σmxz」 or 「Ixy = Σmxz」
When reducing even some small parts of it to a superelement with K4DAMP and AUTOQSET,YES I get slightly different displacements in the higher frequencies range in compare to using no superelement at all, image attached. Is it because the overall reduction…
Take the example file random-xyz.dat from chapter 8 of the dynamics users guide. When I add H5 output to that job I get ACCELERATION and ACCELERATION_CPLX out in the H5 file. ACCELERATION corresponds to the OAGPSDF1 and ACCELERATION_CPLX appears to be…
Let's say that I have complicated model with 100 individually meshed components. All components use solid elements, and none of the components have a contiguous mesh with each other. All components are geometrically arranged such that they all touch at…
Is there a way to either suppress the user warning message 9994 or to direct it to another file so that it can be deleted and the size of the .f06 file decreased?
I have an existing DBALL/MASTER that I want to reuse. I built a few restart jobs and they ran great, reusing the modes and taking minutes instead of hours to solve. Then I did something wrong and the restart no longer works. The FMS is unchanged but the…
F06 file format is changing for each analysis and we could not read the data using common parsing methods. Attached the two formats where character spacing is different for Element ID & Ply ID. Please share us the format details.

What is a good source of information for MSC Nastran High Performance Computing Information with respect to Hardware, Analysis Types, Methods, Memory Settings ?
Hello Community,
I am trying to add fibers to a disc geometry. I used CBAR elements to model them, but it seems like these elements cannot be tension only.
After running the model with CBAR elements, the Bar Stresses, Axial seem empty…
I am trying to compute the geometric stiffness matrices of a model with distributed loading. I would like to export what is being showed in the textbook excerpt below. I am unfamiliar with how to go about exporting this matrix. I can set up the model…
