The following picture demonstrates what should be visible after importing the tutorial project.
1.1 Some Heading
[In case topological sets are required, predefine most of them in the tutorial link so that the user only needs to define a few, this shortens the tutorials a lot]
1.2 Create the Simulation
Hitting the ‘Create Simulation’ button leads to the following options:
Choose Thermomechanical as analysis type and create the simulation.
2. Assigning the Material and Boundary Conditions
In order to have an overview, the following picture shows the boundary conditions applied for this simulation:
2.1 Some Heading
2.2 Define a Material
2.3 Assign the Boundary Conditions
In the next step boundary conditions need to be assigned, for this setup, thermal and mechanical boundary conditions are required.
a. Thermal Conditions
Starting with the thermal conditions, one needs to create a convective heat flux according to the following picture.
After hitting the ‘+ button’ next to boundary conditions there will pop up a drop down menu where one can choose between different boundary conditions.
b) Mechanical Conditions
Don’t worry about the numerics and the simulation control settings, as their default values are optimized according to the chosen analysis type, hence valid for the majority of simulations. If you are a simulation expert however, you can have a look at them and change the settings as you like.
You can use result control to observe the convergence behavior of certain items of interest. In this simulation it is not required.
To get the mesh, we recommend using the standard algorithm, which is a good choice in general as it is quite automated and delivers good results for the most geometries.
The only change you need to do here is changing the sizing to ‘manual’ and define ‘1.8e-3 m’ as a cell size and ‘enable 2nd order elements’. Make sure your setting look like the picture below:
Did you know?
Often, large changes in the mesh’s cell sizes are only spotted in a few regions.
Increasing the global mesh refinements rises the cells drastically.
When using the standard mesher, Simscale offers the option of physics based meshing. This algorithm detects regions which require a finer resolution based on the boundary conditions set.
You can also do this manually, by using one of the local refinement options, foremost being feature, surface and region refinements.
[Add info boxes either about theoretical background or advertising features or other setup possibilities, only for advanced tutorials, though]
The resulting mesh will have about 235k nodes and look like this:
4. Start the Simulation
Now you can ‘start’ the simulation and after about 10 minutes you can have a look at the results.
While the results are being calculated you can already have a look at the intermediate results in the post processor. They are being updated in real time!
[For now only show the interested results and link the pp guide, once the new pp is released write about the potential of the pp , as it covers the value for customers]
Analyze your results with the SimScale post processor. Have a look at our post-processing guide to learn how to use the post-processor.
