Error with Dytran Analysis

[Charoenpon555]

I created explicit nonlinear job in patran and sent to run in dytran.
Dytran showed the error as showed below

%E-P2012401-P2LPTXIX_PUT_SPEC_PNT_TYPE, , ,
Grid point 1906 belongs to element type 4 and 9
This is an unsupported feature. Use one of the JOIN capabilities.
Refer to Dytran User's Manual.

I tried to search in the manual and in the Internet and no solution found.

Does anyone know what is this error and how to solve it ?

Thank in Advance
