Hi All

I am trying to repeat test case SDLS505 (Finite length cylinder, closed ends, shell elements and external pressure) with solid elements. This is with the SDLS505 command file but using MODELISATION=3D.

I have tried it with tets, bricks a SHBs and with a very fine mesh the best answer is still hopelessly out.
Can solid elements be used for an LBA and if so is there an example somewhere?

Thanks in advance.
