Hi,<\/p>\n

 <\/p>\n

I am running a simulation of a steel pipe casted in concrete. In order to reduce the computional cost of the simulation, I have taken advantage of symmetry in geometry, loading, material and the expected response.<\/p>\n

 <\/p>\n

The symmetrical section of the pipe is shown here:<\/p>\n

<\/p>\n

 <\/p>\n

What is the best way to simulate this situation?<\/p>\n

 <\/p>\n

I have tried both to include the concrete in the model and to use fixed supports directly on the ribs on the pipe (leaving the concrete out of the simulation). Either way, the von-Mises stresses in my model does not seem to converge. I have tried to round all sharp corners in order to fix this, but the problem still persists. I have also tried other support conditions in order to avoid stress singularities from arising.<\/p>\n

 <\/p>\n

I have attached a .wbpz-file in case this might help in identifying the problem: https:\/\/drive.google.com\/drive\/folders\/1gQrU1Cj09HNPmTgwvYGFs-C1EuOFRRLc?usp=share_link<\/a><\/p>\n
