I've been recently working on a Knee joint model . I need to find the contact force vector between two particular components.  I have been getting a lot of errors and unable to run the model. 

All the contact pairs and properly defined and I am able to generate all typical outputs except for contact output. please help me out. The output blocks defined so far are node and element outputs for all 8 components defined. 

 

Thanks in advance!

    If you are getting error from Abaqus solver then please contact Abaqus support.

    Hi Bharath,

    Normally for contact forces an output block for contacts is created. As a workaround can you try the same approach in Abaqus?.

    Hello George,

     

    Thanks for the responses,  could you enlighten me with steps to correctly define the output block for contact forces in this case. I have tried but I feel that I am getting it wrong. I need to find the contact force vector between the components. I have defined a Tie contact here. 

    Thanks in advance. 

    Awaiting the response.

    It would be great if someone could just explain me how to properly define the contact output in this case. I feel I am making a mistake there..

    Hi Bharath,

    Please try this:

    You can output this through output block. Check the output option and select the contact output option.

    Thanks George,

     

    What should I enter in the contact output data line for getting the contact force vector on the master surface?

    Hi Bharath,

    In output block manually enter the outputs required.

    A sample deck is also shared.Please go through.

    Thanks George,

     

    I have done the same and run the analysis. When I view the OBD file in Hyper view, I couldn't find vector result in the Results option.  what is going wrong there?

     

    Thanks.

    Hi Bharath,

    It seems like just by giving *node output we can get the vector results.

    Please check the attached *inp and *odb files.
