Hi Manasi,
did you try specifying
vmtksurfaceremeshing -elemensizemode edgelength
when you were trying to specify -edgelength as an option? The rationale is
specifying both the elementsizemode (area, edgelength, areaarray or
edgelengtharray) and then the pertinent quantity (area, edgelength, areaarray
and areafactor, or edgelengtharray and edgelengthfactor).
Hope this clarifies it.
Best regards
Luca
