#### How to use Arbitrary Lagrangian and Eulerian approach in ANSYS

I am trying to simulate the machining operation in ANSYS from the survey Arbitrary Lagrangian and Eulerian approach for meshing was appropriate for this simulation. so how can I incorporate that approach in my simulation model.

It would be good to have more explanation about

what you are trying to do?

what is the process you are using?

what tools you are using?

Please insert images which would be more useful.

I am trying to simulate a manufacturing process which is turning where the workpiece (steel) will be rotating and the tool(tungsten carbide) is stationary I wanted to model the temperature distribution in this process.

I am using Johnson cook material model for flow stress

Sir, what all the information you need?

Hi Subhash,

It looks like an Explicit Dynamics problem as we previously discussed. You can use the Euler domain (set Euler Reference in the geometry details) and change controls as needed in the Analysis settings. Check out this section from the manual for the theory behind it and the coupling?

Sir,

Thank you for responding

I'm getting an error like energy error too large . What might be the cause of it How can I solve it.

Subhash,

Look at the energy conservation and energy summary in the output of your model. This might give you a better idea.

Ok sir,

Can you tell how to incorporate the effect of coolant in the same machining process.

Hi Subhash, As far as I am aware you cannot model Thermal Conductance in Explicit Dynamics, you might have to use WB LS-DYNA.
