Re: [deal.II] Re: Thermoelastic Problem
Prof. Wolfgang, Thank you for the concern and response. I got your point there. I will try it in this way then. :) On Wednesday, August 7, 2019 at 6:38:53 PM UTC+2, Wolfgang Bangerth wrote: > > On 8/5/19 3:40 AM, Muhammad Mashhood wrote: > > The only thing is that I was wondering if I might be using extra > processing > > and memory by defining the fe_temperature, dof_handler_temperature and > > fe_values_temperature by defining them again in the solid mechanics > program. > > And if I am, then would there be any alternative method where I can use > the > > *const SmartPointer > *and *const > SmartPointer > FE_Q > *or something similar**to return *fe_temperature* and > > *dof_handler_temperature* from *HeatEquation* class to *SolidMechanics* > class > > (where they are being used for evaluating q_point temperature as I > mentioned > > above) ?

Thank you! Muhammad, you are in essence asking general C++ programming questions about the difference between regular member variables and pointers, and how to return objects by value, by reference, or by pointer. The answer is that yes, you can do as you suggest above. But I would suggest you take a look at a good C++ book or online resource to understand *why* the answer is yes :-) Best W. -- Wolfgang Bangerth email: bange...@colostate.edu www: http://www.math.colostate.edu/~bangerth/ -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.

Re: [deal.II] Re: Thermoelastic Problem
Dear Prof. Wolfgang, Thank you for your concern and understanding. Yes you are right. I tried something similar instead of copying the triangulation. I used *const SmartPointer >* to transfer triangulation between both thermal and the solid mechanics classes and seemingly the objective of using same triangulation for both parts is full filled also with same refinement and coarsening. While for the sake of using different *dof_handler* for temperature and solid mechanics, I currently have to define again the temperature_dof_handler as well as the fe_temperature objects in the solid mechanics (class) part to do something like following: *dof_handler_temperature.distribute_dofs(fe_temperature);* * cell_solid_mech = dof_handler.begin_active();* * cell_temperature = dof_handler_temperature.begin_active();* (for loop for *cell_solid_mech and **cell_temperature* ) * fe_values_solid_mech.reinit(cell_solid_mech); fe_values_temperature.reinit(cell_temperature); cell_matrix = 0; cell_rhs = 0; fe_values_temperature.get_function_values(temperature_solution, temperature_solution_qpoint); * *fe_values_solid_mech[displacement].get_function_symmetric_gradients(displacement_solution, strain_tensor);* So in this way, I am successful in using the common triangulation for both parts but with different corresponding dof_handlers. The only thing is that I was wondering if I might be using extra processing and memory by defining the fe_temperature, dof_handler_temperature and fe_values_temperature by defining them again in the solid mechanics program. And if I am, then would there be any alternative method where I can use the *const SmartPointer > *and *const SmartPointer > *or something similar to return * fe_temperature* and *dof_handler_temperature* from *HeatEquation* class to *SolidMechanics* class (where they are being used for evaluating q_point temperature as I mentioned above) ? Thank you!

Hope I am clear in my description. > Waiting for your kind response. Thank you in advance! Instead of copying triangulations, you always have the option of just creating the two objects the same, and then refining them in exactly the same way. Would that solve your problem?

None that immediately implements the thermoelastic problem. But there are of course many building blocks you can find in a variety of tutorial programs and code gallery programs.
