Hello to everyone, I'm new here and I'm trying to run a 2D analysis using Drucker Prager model but I'm experiencing a problem about lability, is there someone who please can help me?

I've fixed some errors but i've still a problem in running.. some advice?

1. PRES_REP can be used in 2d or 3d only (reference: U4.44.01), so you need to change the boundary condition.
2. BARR element cannot be used for non-linear analysis
3. There are z values in the mesh, but you are using plane element, so all mesh should be transferred to z=0.

Hello,
according your message file the simulation ended with code 136. One reason for that can be the low memory limit for simulation. Your limit is 2048MB. Try to increase the memory limit.
And as nirmaljoshi wrote, when you use the plane elements you need the z coordinate of nodes zero.

Thank you for your replies!
Wanting to use the model BETON_DOUBLE_DP, the parameter ENER_COMP_RUPT is the fracture energy of concrete GF calculated according to FIB2010 ?
GF= 73 (fcm)^0.18?

Hello,
ENER_COMP_RUPT is the fracture energy in compression not in tension. This value is quite strange. While fracture energy in tension (ENER_TRAC_RUPT) is for standard concretes about 100 - 150N/m and you can compute if with your FIB formula. The energy used in compression is about 10 000N/m. This value is just chosen because I have not found any research paper with testing of compression fracture energy for concrete.
