I am new to the Febio environment (2.6.3 Windows 64). To get warm I am trying to set up a pressurized thin walled elastic hollow sphere (Mooney-Rivlin material) and study the deformation. I have looked at a previous thread (http://mrlforums.sci.utah.edu/forums...=hollow+sphere), but a lot seems to have changed with Febio since 2012 and I can't get this to run.
When setting up the problem from scratch I get the warning "No force acting on the system" even though I've assigned a nonlinear pressure load to the internal surface. I've tried different maximal pressures, sphere dimensions and material properties without luck. In postview no visible deformation can be seen.
When trying the file from the old thread I get the "FATAL ERROR: invalid value "linear" for attribute "pressure.type" (line 9649)" and when changing this to nonlinear, wich I believe to be more appropriate, in PreView I get the "No force acting..." warning again. And, besides this warning, it failes to converge.
I would greatly appreciate if someone could point me in the right direction: What do I do wrong? Enclosed are the febio files I'm trying to get to work (in this particular version the sphere is slightly pinched).
Regards
