Pressure load direction Answered
I have some problem to fix the direction of the propagation (pressure wave) on the interface of two materials. The two materials are water and tissue. I tried to make the wave propagate just in the positive direction (inside tissue), but the wave also propagate in the negative direction (inside water). If I change "water" to "void", then the wave just propagate inside the tissue (positive direction). I used "plod" as follow:
pdef drv1 func
vctr vct1 1. 0. 0.
sdef drv1 vct1 $i2 $i2 $j1 $j2
Would you please help me on this issue?
