- I was wondering what FE method does sofistik use to analyze tensile membranes (transient stiffness or Newton-raphson etc… for both form-finding and static analysis)? I can see in the ASE manual you guys mention that DR is not used.
On pg 59 of the english ASE manual this sentence with “mostly” confuses me whether these listed nonlinear FE analyses are applicable to the form-finding or exclusive for wind analysis:
“Further textile properties are realized mostly by a simplified linear- elastic orthotropic material law. So when the membrane has its normal stiffness e.g. in a final wind analysis, SOFiSTiK makes a normal geometric nonlinear FE analysis (Newton Raphson and Crisfield or line search residual force iteration)”
- I saw your membrane video on youtube and it was very helpful, however I’m not sure where the .sofistik file the gentleman refers to open is?
Any info or help would be greatly appreciated♡! Thank you for your time and patience!
