Improve performance by using different compilers in Dymola
Summary
A good description of how to just install the Visual Studio Build tools is provided on this Dassault Systemes webpage. To support compilation using DASSL, modify the build.bat file by replacing the line: and create an Environment variable called USECLANGCL when you want to use the Clang solver. Note that using the -flto compiler setting can cause the building of the executable to be slow (contact Claytex if you require a solution for this issue). Note that MinGW does not currently support any of the following solvers Radau, Esdirk23a, Esdirk34a, Esdirk45a, and Sdirk34hw (see Dymola Full User Manual Section 5.7.2). Note that the modifications to the build files described above could be done in a more complete and user friendly way; however, they were done this way to keep the changes as small as possible.
