CRAC3D elements

Builder
Builder

 

Hello,

I am trying to use CRAC3D elements in an analysis.

I am doing the following:

1. Build the model and define a solution (106);

2. Delete 8 Chexa elements arround the crack tip (I have 2 layers of elements);

3. Export the model in a .dat file;

4. I close NX

5. O open NX

6. I import the dat file reviously created;

7. I am adding the CRAC3D, ADUM9 and PRAC3D cards:

 

CRAC3D      1133    1000    1859     938     599     598     597    1858+
+           1513    1512    1511    1749                                +
+                                            820     805      44      43+
+             42,    258     988     987     986    1196
ADUM9,64,0,6,0, CRAC3D

......

PRAC3D,1000,1,.5,180

9 After doing this I receive the following message:

And nothing is visible in the working area1

Could you please help me to solve this?
