Hi all, Does anyone know how to automatically rename output sets to match load cases. The default name is: 1..Simcenter NASTRAN Case 1. I have to rename them manually every time and sometimes I have a large number of load cases. If you know how to do this, please share, it would save me so...

Hi all, I'm looking at VM stress results on plate elements (2D) and I get different stress from criteria view vs contour view. I tried extracting results per element, avg on element, max on element, and still getting same result as Criteria View. Where does the Countour View numbers come from...

Hi all, I'm running FEMAP on a new machine and when I run my model it doesn't generate any results, the f06 file is empty but it seems to run. I saw this in the log file: 15:46:53 NSINIT: *** NSINIT ERROR 70 *** UNABLE TO OPEN UNIT 8 What does it mean? What could it be? Thank you, W

Hi, I'm analyzing some fasteners modeled as bar elements, therefore I need to determine the tension and shear on the fastener. FEMAP has output vectors shear forces (in both plane1 & plane2), this is confusing to me. Is this in both directions perpendicular to the bar? I mean there is only...

what are the units for rotational stiffness in FEMAP? specifically the angle units, rad or deg? thanks, W

I'm using DOF springs in my model and I know these elements can generate weird loads in model due to grounding if elements are not aligned with node output CSys. I have such a model right now and I'm trying to figure out an efficient way to find the source of this problem other than visually...

I'm 33 y/o, making good money analyzing private jets interiors structures, bored to death and I feel like I'm working for the devil. I want to do something new where I can find intellectual challenge, be creative and inline with my core values (humanity & the environment). My main problem is...

I have two coincident nodes that I'm unable to merge. Does anyone know why coincident nodes would not show up as coincident when performing the check? Thank you, W

When meshing sometimes I get two tri elements (a quad split in two) where I could have easily a quad. Does someone knows of a way to avoid this? Thank you, W

Hello, I've "unzipped" some nodes along a line that connected two surfaces and now I have the following error message. Does anyone knows what this means? Btw grid point 23 is one of the nodes created after "unzipping". Thank you, W *** USER FATAL MESSAGE 2007 (GP2) ELEMENT 97097...

When I plot criteria stress values, I get maximum value labels on each element. Is there a way to plot average values? I've been going through the different menues and can't find a way to do this. Thank you, W

When I plot my contour I can choose between nodal and elemental. Nodal stresses are much lower. Do you know why this discrepancy? How is "Elemental" calculated? Thank you, Whyowhy

the DOF spring property card doesn't have an option to choose a Coordinate System. How do you define stiffness's in a particular orientation? I've tried defining node output CSys, but I'm not sure if this is right. Thanks, W

Hello Forum, I've been reading about modeling fasteners on the web and all sources suggest to use "spring/damper" elements (CBUSH) in lieu of DOF Springs. My question to you is: What are "DOF springs" used for??? Thank you, Whyowhyowhy

Hello Forum, I'm trying to run a non-linear analysis, but I'm having trouble getting it to converge. I'm constantly getting this msg: *** USER FATAL MESSAGE 4551 (NCONVG) *** STOPPED PROBLEM DUE TO FAILED CONVERGENCE User information: A solution is not possible. Review NLPARM...

Hello Forum, I'm reading output loads on CBUSH elements by listing these loads on the data table, however I'd like to view them on my model as well to help me validate the loads directions and coord/system. So far I'm only able to display reaction loads on constrainst using the Freebody tool. I...

Hi, Does anyone knows where to name your results set before launching your analysis? I always get NX Nastran Case 1 by default and have to rename it everytime. This is kind of tedious when you have a large number of Analysis/Results Sets. Help anyone? Thanks, Whyowhy

Hello Forum, I've been using Femap and Patran on and off for years and my memory gets rusty at times. Could someone refresh my memory on why is it that sometimes we have to check the "AUTOMPC" box in the NASTRAN Bulk Data Options? Is this everytime we're using MPC elements? What does it do...

Hello Forum, I'm trying to define a bunch of loads on multiple noads that I have listed on a table. I have a colum of nodes with their respective loads (x,y,z) and the only way I've found to key in these loads so far, it's to plug them in one by one by selecting the node and then defining the...

Hello Forum, I'm getting equipped to start doing some work from home, including FEM and my plan is to get a Mac desktop computer so I can run both Windows and Mac OS. Have you guys had any issues with this? Do FEM software runs well on Mac?
