## Error saving model and grid generation error

 I was trying out the nice new geometry features of build 20.09.247 - object split and fillet/chamfer when I encountered a couple of errors: a) saving the model and b) doing a grid generation. I began by building a cone frustrum and cylinder, splitting them and then enclosing both in a block: fea.sdim = { 'x', 'y', 'z' }; fea.geom = struct; fea = addphys( fea, @conductivemediadc, { 'V' } ); %% Geometry operations. gobj = gobj_cone( [0 0 0], [1], [0.5], [1], [1 0 0], 'C1' ); fea = geom_add_gobj( fea, gobj ); fea = geom_split_object( fea, { 'C1' }, [0.5 0 0], [1 0 0] ); gobj = gobj_cylinder( [-2 0 0], [.25], [1], [1 0 0], 'C2' ); fea = geom_add_gobj( fea, gobj ); fea = geom_split_object( fea, { 'C2' }, [-1.5 0 0], [1 0 0] ); gobj = gobj_block( [-3], [2], [-2], [2], [-2], [2], 'B1' ); fea = geom_add_gobj( fea, gobj ); I then generated a grid, completed the Equation and Boundary and did some post processing. I then went back to geometry and added fillet and chamfer to the cylinder sections: I attempted to generate a grid and got an error window containing: griggen_error.txtWhen I tried to save it as a model file I got: I was able to save the problem as a matlab script and from it I created the following which will reproduce the geometry: create_model.mThe save and grid gen errors can be reproduced by: 1. running "create_model.m" 2. save geometry in matlab workspace, g = fea.geom 3. from FEATool create new model and import geometry, "g", from matlab workspace. 4. try to save as a model (gets error) 5. go to grid mode and generate grid (gets grid gen error). I will try to narrow it down to a smaller case. Kind regards, Randal PS I really do like the new features!!

## Re: Error saving model and grid generation error

 I must have some kind of an installation problem. After closing FEATool and MATLAB and restarting, I get a fail on saving a single block model. The that starts out the same as the one above "....python...". I can do a grid gen though. Please do not spend any time on this if you think that I may have an installation problem.  Let me re-download, re-install, and re-test.  I may not get to this until tomorrow. But I should have an update within 24 hours.   Sorry for the confusion. -Randal

## Re: Error saving model and grid generation error

 Administrator I have pushed a new update that I think addresses both these issues. First a geometry processing bug for mesh generation. And a check for python for the FEniCS solver that I forgot is checked for at startup (so shouldn't throw error there unless one actually tries to use the solver). Thanks for testing.

 Precise Simulation wrote I have pushed a new update that I think addresses both these issues. Works fine now. Precise Simulation wrote Thanks for testing. Thanks for the features and fixes, -Randal
