Maximum number of variable "valp" one can use in user element

[Dadadong]

Currently I have 18 variables to output, and I did like this in the user element:
          valp(1)=rho
          valp(2)=rho_ele
          valp(3)=rho_hol
           .........
          valp(17)=sigma(2)
          valp(18)=sigma(3) 
Now the output file works just fine, however when feap proceed to get vtk file for paraview, such an error occurs: *** Error in `feap': corrupted double-linked list: 0x0000000001113ce0 ***
when I change back to only 9 valps, it works again.
I did change the "stress" options in umacr04, like this:
          if(foundnp) then
            write(17,'(a,2i10,a)') 'stress',12,numnp,' float'
            do n=1,numnp
              write(17,'(12f30.11)') (hr(begnp-1+i*numnp+n),i=1,12)
            enddo
          endif
and all these efforts didn't work.

So, is there a way to give more than 9 valps?

In your user element you need to set two parameters to increase the number of projected items.  To get the parameters being set include 'strnum.h':

1.  In the 'isw = 1' part:  set   istv = number you want to project (12?)

2. In the projection routine set 'iste = number being projected for this element'

This will allocate the memory feap needs for the projections.
