I was reviewing an MSC presentation on the value of output files. Within that presentation was a listing of the f04 file with an h5 called out as LOGICAL HDF5IN and with FLAGS RA. According to my understanding this means the H5 file is acting as an input…
Hello!
I have 2 models: FEM1 and FEM2, Each of them include BCTABL1 cards: 1 and 2.
I make an assembly of FEM1 and FEM2 simply by including them in FEM3.
Is it possible to activate BCTABL1s 1 and 2 in BCONTACT? Is it possible to merge BCTABL1…
I have flexure that I am using a solution 106 to deflect part of the flexure with an SPCD in steps up to full pre-load. From this pre-loaded state, I would like to add a thermal soak on the pre-loaded flexure from this last load step. There are four thermal…
Hello
I got a warning message about the orientation of CBEAMs (Nastran 2019)

My MSC Nastran SOL101 job crashes because it is unable to find a license. I have my company IT working on it, but they're a little stumped. But, in particular, there's a line in the .log file that says:
Feature NASTRAN not recognized; attempting…
Hello,
I'm concerning with Random analysis using either MSC Random Tool either Nastran.
I have a PSD table (Hz vs g^2/Hz) on wich I need to superimpose a static load expressed in g.
So I have a random "load" plus a static load, how can…
Hi there,
I was wondering if there was a way of outputting shear/traction force and/or stress in the glue patches... Basically trying to "recover" lap shear data.
Hello,
I was running SOL400 in MSC.Nastran V2019.0 and obtained the following message.
What can I do?
*** SYSTEM FATAL MESSAGE 3001 (VDR)
THE INPUT DATA BLOCK NAMED OLB AT POSITION 5 DOES NOT EXIST.

I'm trying to use Python to access Nastran quad element shell forces via the H5 file. I've had good luck with processing SPC, MPC, CBUSH, and BAR forces, but when trying to extract shell forces from a large model my Python script is taking a SUPER long…
Hello,
I'm preforming a space antenna thermal analysis in Nastran with a radiation enclose. When I include the radiation enclose the analysis take a lot of time and resources. There is any possibility to calculate the VF in a separated analysis…
When I did Normal Modes simulation using MFLUID, VMOPT=2, I get below fatal error:
*** USER FATAL MESSAGE 6136 (UDSFA)

I'm trying to load an old model originally created in ANSYS to modern versions of Nastran/Patran. The model was run in ansys - but has the .inp file type normally associated with abaqus. Is there a decent converter I can use to convert these to a bdf…
Hello,
I would like to get a result of total strain and I used NLOUT in SOL400. But I got a following fatal message when I was running MSC.Nastran V2019.0.
*** SYSTEM FATAL MESSAGE 6352 (SoNLOUT)

I am working in solid frame section.In this file i need to turn off element quality while doing the analysis.I just need the result do not consider element quality.
Hello,
I am trying mechanical-thermal analysis using nonlinear coupled physics. First SUBDTEP is HTRAN and second SUBSTEP is NLSTAT. SPCD, TEMP are used for thermal load and static load (FORCE) is used with NLSTEP in SOL 400 (see below). However…
In the .xyd file, the Von mises stress VS frequecny is given, which is from Nastran.
In the .xlsx, my way to find the damage by this sweep.
If there a file to tell how the Nastran embbed vibration fatigue module to find this damage factor?
…
I have managed to get RMS component stresses out with: STRESS(SORT1,PLOT,PHASE,CORNER,PSDF,NOPRINT), although not VonMises. I use FEMAP 2019.1 for post-processing, if that helps.
Are there any issues with having an arbitrarily large and mostly unused set of spoints/qset in an EXTSEOUT run? I'm thinking of possible downstream issues.
Here's a scenario that would lead one to defining a large set of spoints/qset:
