Re: fcVM workbench

can it be used to model foundation on soil with springs? I mean Winkler model? This could be done by modelling the soil as 3D elements or with interface elements (which were available in fcFEM). However, there are two issues to consider: 1) GMSH does not allow generation of interface elements. In f...

Re: fcVM workbench

Its a small effort to reinstate the reinforcement ratio option. something like this? . HH_Blankenese.png . This is at a load factor of 2.0, unfactored concrete compressive strength of 30MPa and unfactored steel yield strength of 240MPa. Comparing this to typical reinforcement ratios in the age this...

Re: fcVM workbench

When I have a concrete structure like the bell tower, would you recommend to use fcvm? I have a bunch of ten hard to read architecture drawings from the last century, no statics calculation, no specification of rebar layout, no specification of the soil. We are planning a antenna system (with housi...

Re: fcVM workbench

I was playing around to see why the CSR in the Wyk_Rohrstoss_linear example is so high and found that it is due to local bending of the tube: . Wyk_Rohrstoss_linear_bending.png . To confirm this I placed a ring on top of the stiffeners to restrict local deformation of the tube: . Wyk_Rohrstoss_ring_...

Re: fcVM workbench

I will try on a windows machine when I find one. Ok I managed to reproduce your error on a windows machine with a fresh set of dependencies. The issue is with the scipy dependency. It was upgraded from version 1.11.3 to version 1.13.0 on conda-forge and this latest version does not play nicely with...

Re: fcVM workbench

I will try on a windows machine when I find one. … in the mean time could you try with sksparse_minimal? 1) > mamba install sksparse_minimal 2) change solver setting in file fcVM.ini (located in the root of the fcVM-workbench directory) from 1 to 3. Also, it would be helpful to know what versions o...
