Create a problemtype

This tutorial takes you through the steps involved in defining a problem type using GiD. A problem type is a set of files configured by a solver developer so that the program can prepare data to be analyzed.
A simple example was chosen, and takes us through all the associated configuration files while using few lines of code. Particular emphasis is given to the calculation of the centers of mass for two-dimensional surfaces. A simple formulation both conceptually and numerically.
By the end of the example, you should be able to create a calculating module that will interpret the mesh generated in GiD Preprocess. The module will calculate values for each element of the mesh and store the values in a file in such a way as they can be read by GiD Post-process.

Access the .post.res file to see the format, and check the documentation about the Postprocess data files in the Customization manual.
It's time to change to postprocess and see our results. Go to View results in the menu, contour fill > MC-DISTANCE
You should see something like this, but adapted to your generated geometry:

Extra: Wizard problemtype example

The current course focuses on a 'tree distribution' of the information. There is another example that implements a 'wizard distribution', based on this tree one. You can find the wizard one on our Github site.
