A problemtype is the set of configuration files that permmit to adapt GiD to any simulation code. It must have the analysis code included and properly connected to GiD.
Problemtypes that are to be installed on the server are exactly the same that would be used to execute from GiD locally. So, if a problemtype works correctly when it is used by GiD to run in the local computer, it can be directly used in the server.
To install problemtypes on the server, copy them to the subdirectory problemtypes in the procserver directory.
Note 1: Take into account that the executable included inside the problemtype must be a proper executable for the computer where procserver is running.
