Hi, I tried to set different solid materials by calling Ground Group 11. Code used as below:

Q1 Group 11 conpor(elec1,-1,cell,5,7,12,19,6,9) init(elec1,prps,0.0,grnd)

in ground, C--- GROUP 11. Initialization of variable or porosity fields C Index VAL

CALL FN1(VAL,162)

11 CONTINUE

RETURN

But the error appears as: GROUND called but no initial value set! INDVAR = 146 Group No= 11 Sectn No= 1 Patch NAME in INDATA=ELEC2

this error should be straight forward, but wierdly, after many trials with different settings, still unable to resolve. Please help.

Try changing the sequence to

11 CONTINUE CALL FN1(VAL,162) RETURN
