Hello, I have encountered a very odd error in my analysis. I got an error saying "***ERROR: Excessive rotation of node number 154156" while the listed node doesn't even exist in the model. I opened the .inp file and searched for "154156" which gave me no matches. I'm using the "initial state"...

Hello everyone! I'm performing an SPH analysis of the airbag impact. It's equipped with an exhaust vent. The simulation goes well until some point in time when some rapid increase in kinetic energy of the fluid can be observed (it is unjustified and maybe it's a kind of an artifact or the...

I'm trying to define a reference mesh for my explicit analysis, but I want to define my model in terms of Parts and Instances in Abaqus CAE and then write the "*Initial conditions, Type=NODE REF COORDINATE, Input=xxx.inp" line in the inp file. The problem is that Abaqus will not let me to do...

I want to conduct a simple tensile analysis of a rectangular sample and get the corresponding force-strain curve. I know that I can measure the reaction force at nodes which belong to the displacement boundary condition. However I want to get also the force values measured somewhere in the...

I'm encountering some warnings while executing the import analysis and wondering if it's possible to get rid of them. The first Explicit analysis is the case where some airbag is filled with gas to some specific pressure value. The modelling approach is to use the fluid cavity. In order to...

I have a question about the theory standing behind the application of enforced motion in ANSYS. It can be found in Mechanical APDL Theory Reference (14.18 -- Enforced Motion in Structural Analysis). I am interested in the first two of them: 14.18.1 -- Full Full Method for Transient and...

Hello guys. I'm wondering if it is possible to get the spline equation created in AutoCAD. Does anyone know something about this?

Hello guys I'm wondering if it is possible to get the spline equation created in NX. Does anyone know something about this?

Hello guys. I'm creating some part in CATIA v5r19 and I'm a bit confused about one of it's nuance. I created some sketches and want to divide some of them to couple of JOIN's. Sometimes I simply click JOIN and just pick lines from sketches and sometimes as I click on some line CATIA picks whole...
