The mixed equation solver combines the advantages of the PCG and sparse solvers while minimizing their downsides.

For information on the mixed solver, see The Mixed Solver in the Basic Analysis Guide and EQSLV.

Use the MIXOPT command to specify the precision of the mixed solver computations. MIXOPT is a beta command that can be used through a Mechanical Command Snippet or by manually editing the Mechanical APDL solver input files.
