The following example

*NODE
1,0,0,0
2,1,1,0
*ELEMENT,TYPE=B31,ELSET=Eall
1,1,2
*MATERIAL,NAME=Material
*ELASTIC,TYPE=ISOTROPIC
210000000000,0
*BEAM SECTION,ELSET=Eall,MATERIAL=Material,SECTION=RECT
0.15,0.1
-1,1,0
*BOUNDARY
2,1,6,0
*STEP
*STATIC
*END STEP

fails with 

*ERROR in cascade: zero coefficient on the
        dependent side of an equation
        dependent node: 14        direction: 3

but it shouldn't. image

Hi Victor,

I think I found a solution to that. Do you allow me to include your simple examples in the test suite?

Thanks for all your contributions, they are very valuable!

Best Greetings,

Guido
