  How to slove the "Warning 30064 (INI+64) material 140 is not included for silent boundaries"?
  I use the keyword "BOUNDARY_SALE_MESH_FACE" to set the no reflective boundaries. When I run the program, "Warning 30064 (INI+64) material 140 is not included for silent boundaries" appears.How can I slove this problem?

  You can ignore this warning for mat 140 (vacuum). This warning is generally triggered when bulk or shear modulus is set to zero.
