mkl_rt.dll is a dynamic link library file that is part of the Intel Math Kernel Library (MKL) runtime. The MKL is a highly optimized library of mathematical functions, designed to help speed up computation on Intel processors. The library includes functions for linear algebra, Fourier transforms, random number generation, and more.
Many software applications, including ANSYS, use the MKL library to improve their performance on Intel processors. mkl_rt.dll is the runtime component of the MKL library, which means that it is responsible for loading the library into memory and providing access to its functions.
If you encounter an issue related to mkl_rt.dll while using ANSYS or another application, it may be due to a problem with the MKL library installation or configuration. Updating or reinstalling the library may help resolve the issue.
