Hi, I’m a current student in Australia. My project was to take out the mesh from the stretch film for analysis, but there was a problem when analyzing the cable mesh in Karamba. When I change the material of the cable to glass fiber, the pressure of the cable will be very high.
I haven’t found out what caused it so far. Does anyone know what caused it?
Thank you for your help.
Thanks，
Davy
my opinion is just based on observation and might be completely useless,
since glass fibre has as a higher tensile strength than steel for instance, the second image that has messed up vertices looks to me more relaxed which could make sense, maybe you have to adjust reiterate some other settings/components to compensate the intense change of tensile strength.
thanks for your reply, I’ll try it
does anyone have any suggestions? my Karamba still failed to analyze.
Hi @DD15,
the cable-net is partially under compression which causes the weired displacement patterns (see here:
A2 cable net_cp.gh (653.9 KB)). You could try to use a soft dummy material for the boundary cables and load it with a high strain. In this way you can simulate a frictionless tendon.
To simplify debugging, consider reducing the number of elements in your working model and only compute the full version in the final step.

Thank you very much for your reply. This solution works.
