I have used FSAM to model a shear wall. The element that i used is isoparametric quad element. I want to find cracking_angles for it. I used following command
recorder Element -file cracking_angles1.out -time -ele 9 material $mattag cracking_angles
I dont know what I should enter as mattag so I tried entering numbers from 1 to 5. I got different values for 1 to 4 and got no values for 5. The documentation available also isnt clear. Please tell me the correct way.
