I am confused by not being able to solve this equation in Comsol
This is equation I mention:
1-2*sqrt(Lf/pi)*integrate((1)/sqrt(Lf^2-x^2)*(1+0.3*(1-x/Lf)/(1+Lf/0.1)),x,0,Lf)
If I write it in ODE and run, Comsol will notice message error (division by zero)
If I add eps right after like this (Lf^2 -x^2 +eps), Comsol runs ok but result I get absolutely wrong
Any idea about my problem ?
