first, the .tcl code is calling FemussEvalDirichletCondition but your proc is called EvalDirichletCondition I assume that it has been a mistake writting the question in this forum, in any case check that you are calling the proc that do you really want It seems that EvalDirichletCondition expects as...

This surface has been created as a 'planar rectangular shape' trimmed with the curves. (it as been detected as possible planar within a tolerance) Do you have exactly 4 lines, it is possible to force to create a non-planar and untrimmed surface. You can convert the current inner shape of your surfac...

1) Check in Utilities->Preferences... Graphical->System if do you have set "Fast visualization mode" or "Safe visualization mode" If possible try to set the "Fast" option to use OpenGL with the drivers of your graphic card otherwise will use OpenGL by software, and some...

attach a zip file with the .gid folder of the model, to see how are your curves and the created surface The 'unexpected' (but valid) shape of the elements depends on the parametrization of the surface The surface could be defined in different ways, 1) as a plane trimmed with the curves, and then cou...

The Tcl procedure could be this (save it in a file named <problemtype>.tcl to be automatically sourced) proc MyGetEdgesFromQuadrilaterals { } { set info_mesh [GiD_Info mesh Elements quadrilateral -sublist] #use and face_id array to avoid repeated and store an id foreach item $info_mesh { set connect...

GiD mesh data structures are not oriented to faces, the faces of the elements doesn't exists or have an identifier number. To write what you want you must do it with some Tcl scripting procedure that get the information of GiD (nodes and elements with some "GiD_Info Mesh ... " command) and...

It exists an option Mesh->Mesh criteria->Force points to->surface mesh... Unfortunately doesn't exists an option like 'force lines to', but maybe the first one can aid you. First use the tool Geometry->Edit->Divide lines->Num divisions (or Length) to divide the crack lines to create points at simila...

Rename This is not a simple change of name of a layer: you don't have one layers, you have two layers: abc (without parent) and xyz (with parent layer=abc, its fullpath name is abc//xyz) then you must do two steps: 1-change the parent of xyz to none 2-delete the layer abc 'Layers ChangeParent abc//x...

Write what you want is trivial in GiD, but at least strictly in theory it won't be a valid STL format!! Although I think that some programs are doing it (write more than one solid block) and GiD also is able to read STL with multiple solid blocks (without assume the block name as a layername) To do ...
