Problems with mesh generation Feap85 vs Feap74
« on: August 01, 2019, 07:57:49 AM »
Dear all, please you can find in the attached file an input  correctly running with Feap74 and giving the error message *ERROR* BLKGEN: Insufficient storage for nodes-  final node =*****     numnp =13824 with FEAP85
I tried both thermal and mechanical linear problems.
Could you give me some suggestions? It seems that in the subroutine blkgen ng exceeds numnp.

The problem is a current limit on the number of blocks you can generate with the counting of PARTS.

To fix you can change the common block: p_ptname.h and change dimensions form 1000 to 10000 (2 places).

Then in ./program/ppart.f  change the formats 2000 and 2001 for the i3 to i4.

The "10" at the end of the block 'cart' means what?  If it the element type it may be in the wrong place.  Newer versions of feap prefer you to give the block commands as

BLOCk
  CART  n1 n2 n3 0 0 ma
     BRICk 8  or the type you want
       ....
