On a QUAD 1x1, pinned at all nodes ( see the image ), I apply a constant pressure-traction (PLOAD4) at x-direction, with a magnitude of 10. The Tx reactions on each support is 2.5 as expected. Total X force = 10*1*1=10. Each support takes 10/4=2.5.
I create a Cylindrical Coordinate System...
I have the oppurtunity to work for a company that develops a Finite Element Solver. I must choose between the next two:
1) Programming of FEM method etc, with C, C#.
2) Performing analyses to check if the solver works properly.
I have worked as a structural engineer, 10 years now, where I have...
Hello,
I have a model with solid elements, simulating a clip, as you can see in the image below. In SOL 601, with NxNastran, I can easily simulate the male clip moving out from the female and in again with a transient analysis, as you can see in the images sequence. But when I try to perform...
I tried many to times to run an Explicit analysis, but I think Femap doesn 't behave as it should, or better, as other Explicit solvers do. Like LS-Dyna or Abaqus.
I tried to do something like this http://www.dynaexamples.com/intro-by-j.-reid/symtube (select the animated result to see it...
Hi everybody!
I 'm trying to perform a contact analysis. As you can see in pics 1 and 2, I 'm trying to pass the ball through the 2 plates. I do the followings:
1) Plates and ball from shell elements
2) Displacement assigned on ball, not force.
3) SOL 601 Non-linear static, not transient
4) ATS...

Hi everybody!
I 'm a civil (structural) engineer. I have an oppurtinity to work for a company which develops a FEA software (pre/post processor and solver), as a Software Testing Engineer.
I 've read many things for this job in the internet, but nothing had to do with a FEA software. All the...
Hi,
I 'm working for years Femap, since 9.3 version and I didn 't ever faced such a problem.
On Femap 11.0.1, I perform a buckling analysis to a compressed steel member (HEB 240), just to give geometric imperfection from the first buckling mode, as I always do.
For example, for a compressed...
Hi everybody!
I want to model many steel connections in Femap, but every connection needs a lot of time to design it (Bolts, endplates, holes etc). Does anyone knows, if there is a design program, that you can model easy any connection you want, and then export it as a 3D Solid model, so that...
Does the SOL601 support the Edge to Surface glue contact? When I perform a static analysis it 's working fine, but when I perform an advanced nonlinear static (601) it doesn 't work...
I would like to import Rayleigh Damping for Advanced Nonlinear Transient (SOL601). My steps are:
- In the "Analysis Set Manager", I press "Preview Input" and then I click "Edit Preview"
- At the exististing PARAM commands I write for example "PARAM,ALPHA1,0.5"
- Click on "Analyze" and I take...
How we perform a rupture analysis? I set a bi-linear stress-strain curve, nonlinear material, large displacements-large strain etc, but the analysis always stop. Can someone give me some advices on how I can achieve that? Thanks.
Hi!
I perform a simple time history analysis with Femap-NxNastran. One time with Direct Transient and one with Modal Transient. When I perform the Modal Transient the Animation is wrong and very weird...I can 't understand why is this...
Just check the 2 attached videos.
Thanks
Hi everybody!
I perform an anvanced nonlinear transient analysis with contact elements. How I give damping to elements? For example I want to force a ball by gravity and throw it to the floor. Well, I can do it, but without damping. How I do it? Also how I can give different damping to the ball...
