    Inventor Nastran Error 5059

    Found a solution. Apparently, a distributed force (in N/mm) is not acceptable in this case. I changed the load to a force (in N) acting on the same edge, and the solver works without problems.

    Inventor Nastran Error 5059

    Hello all, I have started working with Inventor Nastran just recently (I have only little previous experience in FEM) and I am facing problems in setting up a load case for a cylindrical structure. I constructed the structure as a cylindrical surface and generated a shell mesh with a laminate...

    Minitab: Normal Plot of Standardized Effects - Interpretation

    "Calling all Six Sigma Black Belts!" Hi everyone, I am trying to evaluate testing results using Minitab. I would like to use the graphical method "Normal Plot of Standardized Effects" to vizualize how the test result is affected by a number of factors. Here's an example of what this plot looks...

    Re: Plotting Strength ratio of composite with param SRCOMPS (Nastran 2018.3)

    thread825-222534 "To whom it may concern" Hi all, I am referring to the above thread titled "Plotting Strength ratio of composite with param SRCOMPS" from 2008/2009. It has helped me calculate strength ratios (SRs) in Nastran 2018.2 while using Hypermesh and HyperView 2017.3 as pre and post...

    Composite Failure Analysis using MSC Nastran / HyperMesh

    Hi everyone, I have found a solution. In HyperMesh, I set PARAM,POST,-1 and GLOBAL_OUTPUT_REQUEST,STRESS(SORT1,PUNCH,REAL,VONMISES) and GLOBAL_OUTPUT_REQUEST,STRAIN(SORT1,PUNCH,REAL), so that .op2-file is created. To make sure that all Nastran results are kept, I entered "scratch=no" when...

    Composite Failure Analysis using MSC Nastran / HyperMesh

    Update: I got the Failure Indices to appear in the F06-File. The reason for them not appearing was that under "Load Steps > Subcase Options > DISPLACEMENT" and "Load Steps > Subcase Options > STRESS" I had "FORMAT" set to "PLOT" instead of "PRINT". However, I am still unable to view the failure...

    Composite Failure Analysis using MSC Nastran / HyperMesh

    Hi all, I am new to this forum and have a question concerning composite failure analysis. I wasn't able to solve my problem with the existing threads, hence this new one. I am currently working on a sandwich structure which is made from an aluminium honeycomb core and carbon fibre UD/epoxy...
