WebFor Negative (<0), the stepping stops if the real part of the expression becomes negative (comp1.intop1(comp1.T)-360, for example). Another example of a stop condition is timestep<0.04, which makes the solver stop when the internal time step drops below 0.04 s (when the time-dependent solver hits a sharp transient, for example). WebFrom Equation 1, we see that to calculate the fluid force on a surface Comsol needs to integrate the stress vector 6 + over the surface. We can write this as (+ L µ c J Ü⋅Π é. g + æ è å Ù Ô Ö Ø @ 5 Ì L µ 6 + @ 5 Ì (8) (+ L µ L spf.T_stressx spf.T_stressy spf.T_stressz M ë …
