Abaqus Fictitious Surfaces for Beams -- Help
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.
keywords error in vumat
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.

Co-simulation engine error
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.
how to convert total lagrangian tangent stiffness to corotational
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.
