Hi Developers,<br>
<br>
I am tracking time history of variables on particular vertices
on the<br>
fault. However, I found the vertex ID in Pylith (v_fault) is
larger than<br>
the total number of vertices on the fault. How can I convert
the value<br>
of v_fault back to the vertex location on the fault surface?<br>
<br>
For example, I got the following fault opening error message<br>
WARNING! Fault opening with nonzero traction., v_fault: 4154,
opening:<br>
1.03716e-10, normal traction: -0.0042952<br>
mpinemesis: faults/FaultCohesiveDyn.cc:382: virtual void<br>
pylith::faults::FaultCohesiveDyn::integrateResidual(const<br>
pylith::topology::Field<pylith::topology::Mesh>&,
PylithScalar,<br>
pylith::topology::SolutionFields*): Assertion
`fabs(tractionNormal) <<br>
_zeroTolerance' failed.<br>
[0]0:Return code = 0, signaled with Aborted<br>
<br>
v_fault points to vertex ID 4154. The total number of vertices
on the<br>
fault is 1472, however.<br>

refers to the full</div>
<div>mesh vertex numbering.</div>

Hi Matt,<br>
<br>
Do you mean the v_fault not only represents the ID of vertices on
the fault, but any vertex in the volume/full mesh?<br>
<br>
If that is the case, I know where I go wrong.<br>
