This example illustrates the creation of a Gmsh file for later visualization with Gmsh. The part of the data file specific to the “writeGmsh” function call is as follows:
# Group creation :
meshGrp=db.getGroupAllFEM
targetGrp = db.getGroupCopy("pan_PZ_Al_2024")
targetGrp2 = db.getGroupCopy("pan_PZ")
# Stress data in skins :
stress = db.getResultCopy("TEMP_GRAD_X","Statics",\
"Stress Tensor","ElemCenters",targetGrp,[])
stress2 = db.getResultCopy("TEMP_GRAD_X","Statics",\
"Stress Tensor","ElemCorners",targetGrp,[])
displ = db.getResultCopy("TEMP_GRAD_X","Statics",\
"Displacements, Translational","Nodes",targetGrp2,[])
norm = displ.deriveVectorToOneScal("abs")
# Stress data in honeycomb :
targetGrp =tmpGroup_Honey_72
honeyStress=db.getResultCopy("TEMP_GRAD_X","Statics",\
"Stress Tensor","ElemCenters",targetGrp,[])
# Gmsh output :
db.writeGmshMesh("brol.msh",0,meshGrp,false)
db.writeGmsh("brol.gmsh",0,[[stress,"stress","ElemCenters"],\
[stress2,"stress2","ElemCorners"],\
[honeyStress,"honeyStress","ElemCenterPoints"],\
[displ,"displ","Nodes"],\
[norm,"norm","Nodes"]],\
[[db.getGroupCopy("pan_PZ"),"mesh pan_PZ"],\
[db.getGroupCopy("pan_MZ"),"mesh pan_MZ"],\
[db.getGroupCopy("pan_PX"),"mesh pan_PX"]],\
[[meshGrp,"skel sat"]])
In fact, only the last function call is new. The example is provided in file "RUBY/EX11/writeGmsh.rb".
