Hello, 

I am trying to use DRESP3 responses with DCONSTR in a simple example, in order to compute the constraint the density of neighbours elements of each elements.

 

However, when I am running my optimization I encounter this error:

 "*** ERROR # 1898 ***
 Approximated constraint 1 does not match with response 3 at the
 first iteration.
 Approximated constraint =     1.8000000000e+00
 Approximated response   =     9.0000000000e-01.
  
 
 *** INTERNAL PROGRAMMING ERROR ***
   in file "conapp.F", at location # 5763." 

 

Find attached my .fem file, other relevant files.

 

Best regards,
