How to set element density on the lines if line IDs are available?

Altair Forum User

How can I set element density for two shortest lines of a rectangular surface and leave the other two lines with the default element density based on predefined element size?

 

I have the line IDs.

 #Selected Surface set surfIDs [ hm_getmark surfs 1] *createmark lines 1 'by surface' {*}$surfIDs  #Line list  set lineList [hm_getmark lines 1]  #Line IDs set lineId1 [lindex $lineList 0] set lineId2 [lindex $lineList 1] set lineId3 [lindex $lineList 2] set lineId4 [lindex $lineList 3]

Hi,

try this script:

 set Density1 5 set Density2 10 *deleteelementsmode 2 *createmarkpanel surfs 1 'Pick a surface:' if {[hm_marklength surfs 1]==1} {     foreach LineId [join [hm_getsurfaceedges [hm_getmark surfs 1]]] {lappend LineList [list $LineId [hm_linelength $LineId]]}     set LineList [lsort -increasing -real -index 1 $LineList]     lassign [join $LineList] Line1 -> Line2     *setedgedensitylinkwithaspectratio -1      *elementorder 1      *defaultremeshsurf 1 [hm_getelementsize] 2 2 2 0 1 1 1 0 0 0 0      *createmark lines 1 $Line1     *change_edgedensities 1 1 $Density1 0     *createmark lines 1 $Line2     *change_edgedensities 1 1 $Density2 0 }
