CentOS 7.6 is not supported in current versions. It's planned to be supported in 2019R2 but still not 100%, ref:

If you can find other machine with supported OS as shown in the doc, that would be ideal. If not, make sure you are using ANSYS 2019 R1 

In either case, make sure you have all prerequisites installed according to Chapter 2 of the Linux installation guide

Aside from the OS and prerequisites, your graphics card is also not supported, ref:

for this issue, you can try the following workaround (change version and installation path accordingly)

export LIBGL_ALWAYS_INDIRECT=1

export LIBGL_ALWAYS_SOFTWARE=1

export LD_LIBRARY_PATH=/ansys_inc/v193/Framework/bin/Linux64/Mesa

/ansys_inc/v193Framework/bin/Linux64/runwb2 -oglmesa

Thanks,
