Press fit analysis

Recommended Posts

Hi Nachiket,

I think the solver has to perform the iterations until the full  load is reached. But since 15 hours it is in the same 92% load iteration. No Increment in the load. What is the problem?

 

Thanks and regards,

Punith

@Punith Never encountered such a problem. How much time it took for the solver to reach 92%?

@Prakash Pagadala

ok I understand that. Thank you for the reply.  Now to avoid such a mistake next time how can I export the intermediate results. For example the solver has performed the iterations upto 92% load now and looking for convergence. But I would like to see my results at 91% load. How can I do that?. Please help me.

To view previous iteration you can use NLOUT.

Yes, you can still use NLOUT and also you use NLMON to monitor Nonlinear simulation

But NLOUT is already used in the model. I do not see any H3d file in the location.

For that in control card you need to switch NLMON=Disp.

As far as i remember NLOUT= write last non convergent file

and NLMON= write all iteration in seperate H3D

Correct me @Prakash Pagadala if i am wrong?

I have a question regarding axisymmetric analysis. Is there any option available in Hyperworks for axisymmetric problem like in Abaqus?.If not, is Hyperworks working on that?.

I have a cylindrical component andI would like to mesh only 2D crosssection of it and finally see the results for 360 Degree. How can it be done?. I tried defining the symettric constraints for the 2D mesh and defined the line contacts between the mesh. But it is not working. I contacted Hyperworks-Germany support team and they said that line contact is not working with Optistruct. How can I solve my problem? I am not able to work with 3D model as it is taking lot of time. Please help me in this concern.

 

I am basucally looking to some parameter study for pressfit analysis of rim and disc by varing the length of press fit and angle and I am looking for the optimum. I think this problem can be handeled in Hyperstudy. This problem is non-Linear and if I work with 3D it takes huge time.

 

Please help me in this concern.

 

Regards,

Punith

Hi Punith,

 

Is it possible to share the axisymmetric problem from Abaqus (PDF should do)?

 

I will check if I have any information.

Hi Punith,

 

This is possible in RADIOSS 

 

Here is a reference: RD-E: 0800 Hopkinson Bar

Hello@Prakash Pagadala ,

I am just asking about the file for the Hopkison Bar as the example requires the input file.

Input File

High_strain_rate: <install_directory>/demos/hwsolvers/radioss/08_Hopkinson_Bar/High_strain_rate/SHPB_H*

Low_strain_rate: <install_directory>/demos/hwsolvers/radioss/08_Hopkinson_Bar/Low_strain_rate/SHPB_L*

 

Thanks!
