1 - Download GiD from CIMNE.

2 - After installing, put folder formfind.gid inside GiD folder problemtypes. Download the computer source code written in Ada95.

The solution parameters are available inside GiD through Data --> Problem Data.

**lstol**: Controls the accuracy of the line search. It must lie in the range 0.0
<= lstol < 1.0. Decreasing this value tends to increase the accuracy of the line
search. It is usually 0.1.

**maxls**: The maximum number of cubic interpolations allowed in the line search.
It must be greater that one. It is usually 20.

The iterations terminate if the infinity norm of the residue becomes less than or equal to maxnorm, which is calculated as:

**maxnorm = mntol * mnref**

If **mntol** is specified as a non-positive value, it is replaced by 0.001.

If **mnref** is specified as a non-positive value, it is replaced by the infinite
norm of the residue, evaluated with all displacements equal to zero.

**maxminor**: The maximum number of minor iterations allowed. If maxminor is
specified as a non-positive value, it is replaced by ten times the number of
degrees of freedom.

**maxlist**: The number of BFGS corrections kept. These corrections are stored
separately on a doubly linked circular list. Used only with the limited memory
BFGS method. It is usually between 3 and 20.

**maxmajor**: The maximum number of major iterations allowed. It must be greater
that zero.
