    linear analysis on wood material

    Hi, I am using MAT9ORTH card for material property. and for physical property PSOLID has used. getting error as shown below picture. Please give suggestions, how to eliminate this error. Thanks and Regards, Narasimhamurthy

    Hi, Need to perform fatigue analysis is FEMFAT. Static analysis has performed in Radioss. now static analysis stresses are used to do fatigue analysis. how to carry static analysis results from radioss to FEMFAT. If you have any study material on this, Please share. Thanks, Narasimhamurthy

    Geometric nonlinear - implicit

    Hi, this is confidential model . so i can not share. please find attached .output file. There is friction coefficient between sheet metal and concrete. please share possibility of error. Thanks 3085351_48_27IN.out

    Geometric nonlinear - implicit

    Hi, Is possible to perform Geometric nonlinear - implicit with Gravity load? because getting ISTOP=0 error. ENGINE ERROR: ** ERROR : RADIOSS IMPLICIT STOPPED DUE TO LOADING DATA ** Thanks Narasimhamurthy

    Gauge optimisation

    Hi, Is need to extract mid surface of sheet metal for gauge optimisation?? here optimisation is performing on shelf assembly, shelf pan has bends and holes. since all mid surfaces are not importing. how to import all mid surfaces without loss?? Thanks and regards Narasimhamurthy

    How to apply torque/moment.

    yes, Direction is good but rotating point is different.

    How to apply torque/moment.

    Block is not rotating about rigid body master node axis, where we specified torque. Rigid body moved near to block.

    How to apply torque/moment.

    yes, have applied in concentrated load only.

    How to apply torque/moment.

    Hi, I have created a block with Hexa elements and shell elements with rigid body at 1 mm distance from block. please find attached image file. Block is going to impact over rigid shell with 50 N-mm of torque. Type-7 contact is defined between block and shell elements. problem is solving without error but in contour plot rigid body moved near to block and block is swinging. as shown in below picture. is there any method to define torque in Radioss? Thanks and Regards Narasimhamurthy

    Thank you very much. In initial velocity load collector, I have assigned GROUND-COMP SET in ground id, here set was created by COMPONENTS entity. now changed to GROUND NODE set and set created by NODES entity. it is working.

    Hi velocity is -13.3 m/sec in Z-direction. please find attached starter file. TubeCrush_0000.rad
