hello Dear friends
I have one question about corotational concept. is it possible to obtain tangent
stiffness matrix by TL approach and updating degrees of freedom(including displacement and
rotation by corotational. please aware me of related papers.

All,
Hello. Looking to create a fictitious surface around an Abaqus model that uses beam elements for the purpose of transferring pressure loads from CFD to the beam. We are restricted to using beam elements; indeed, structure is a very long and thin beam.
What is the easiest way to do this?
Most grateful for your help.
Dear all,
I constructed a VUMAT subroutine which including 4 state dependent variables, so I wrote "*Initial Conditions, Type=Solution" in keywords. But, when I run the simulation I get this error:
in keyword *PERMEABILITY, file "Job-vumat2.inp", line 102: The keyword is misplaced. It can be suboption for the following keyword(s)/level(s): material
Analysis Input File Processor exited with an error.
Could anybody help me? Thanks a million.

I am operating a co-simulation analysis in Abaqus. This a kind of interaction between fluid and solid so I am doing co-execution. Unfortunately, when the program run up suddenly I encounter this error " Error in job Co-execution-3-Model-1: Co-Simulation errorError in job Co-execution-3-Model-2: The partner program in the co-simulation has issued a fatal error message.
hello Dear friends
I am working on large displacement of euler beam. I used total lagrangian approach. because of field consistency between degrees of freedom(displacement and theta) tangent stiffness matrix depends on tangant theta and consequently becomes singular for theta=90. so I am seeking for a method to overcome this problem. I believe that the solution is to remove rigid body rotation from analysis. please correct me. is this reasonable. if yes how should I remove rigid bodu rotation
best regards.
