I am new to LS-Dyna and i am trying to simulate a blade impacting wood.
The geometry is 2D and i am using ERODING_NODES_TO_SURFACE Conatact type in which the master is the node list of the blade and slave is the wood which i Have selected using its part ID.
For Material I am using MAT_POWER_LAW_PLASTICITY for both blade and wood with additional MAT_ADD_EROSION on wood
I am getting the following error as soon as i run the simulation
Error 20211 (STR+211)
reading contact segment data
undefined node # 0
13127 0 0 111111 0
input phase will continue if possible
The node mentioned is at the extreme end of the rectangle which I have created for wood.
Please provide any input as to how I can sove the problem.
