Questions of fault parameters

Dear Pylith team,

We specifies fault parameters in terms of lateral motion, reverse motion, and fault opening as shown in Figure 1.

I have observed the fault results of the output file of examples/3d/hex8/step03.cfg. The slip in the x direction corresponds to the left-lateral-slip and the slip in the y direction corresponds to the reverse-slip as shown in figure 2 and 3.

This appears to be a mismatch with the direction specified in Figure I. I think that the left-lateral-slip should correspond to y direction and the reverse-slip should be z direction.Is there something wrong with my understanding?
Thank you in advance.


ParaView will label the components of any vector as x, y, and z. In the case of slip, the components are actually left-lateral, reverse, and fault-opening.
