[GiDlist] handling multi-material elements

[Rafael Doig]

Hello together,

I need your help for following "plotting"-problem:

Multi-material elements can have more than 1 material. In attached
illustration, a simple model with 3 elements, two materials has been
drawn.

1. Left element is filled (100%) with material 1.
2. Right element is filled (100%) with material 2.
3. Center element is mix-filled: 60% with material 1 and 40% with material 2.

I want to let GiD plot the center element in 2 colors as the
illustration shows. Some idea how to do that? Is it possible at all in
current GiD version (Linux: 7.7.2)?

As for the left and right element I do following:
1. I make a range table:
- 0.0 - 1.0 : material 1
- 10.0 - 11.0 : material 2
2. if f1 is equal 1.0 then fillingrate f = f1
if f2 is equal 1.0 then fillingrate f = 10.0 + f2

I works well. Unfortunately for the center element does not.

Thank you in advance for any suggestion
Rafael
