The first SimScale update of the year has just rolled out. It allows users to take advantage of advanced thermomechanical analysis and includes a few other new simulation capabilities. Find the highlights of the latest release below.
Advanced Thermomechanical Analysis
We’ve seen a high demand for thermal and coupled thermomechanical simulations among SimScale users, which is why these capabilities were significantly enhanced with the latest platform update. A new analysis type enables in-depth studies of mechanical parts under thermal and mechanical loads, such as transient heating/cooling, collapse due to fire exposure, thermal shocks, shrink fit and much more.
Advanced mechanical and thermal analysis features, such as:
- temperature-dependent material data
- powerful boundary conditions, such as follower pressure and remote force
- frictional contact
- dynamic effects
were combined into one streamlined simulation workflow. The animation above shows the temperature and stress distribution of a stop valve that undergoes a thermal shock due to a hot fluid. The initial state shows the pre-stressed bolts followed by the high-temperature and high-pressure fluid entering the valve. Physical testing of such extreme conditions would be very expensive and time-consuming compared to virtual testing.
Another application of this type of thermomechanical analysis is shrink fitting. In the image below, the shrink fit between a tool and the tool holder is simulated. The resulting stresses within the connection are then analyzed. Check out the public project here.
Fan Boundary Condition for CFD
Fans are important elements in the heating, ventilation and air-conditioning (HVAC) systems that are regularly simulated on SimScale. Typical examples are data-center cooling, comfort factor analysis within rooms, or fresh air supply in parking garages or tunnels. The new fan boundary condition generates significantly more accurate representations of fans within such flow simulations. It can be used at both inlets and outlets to drive the flow in and out of the domain. The fan curve—which governs the relationship between pressure jump and flow rate—can be explicitly specified via a table to accurately predict the impact on the surrounding air.

Since the release of the Community six weeks ago, more than 2000 public projects have been created. These are a great resource for learning and users can copy and reuse projects for their own purpose. Hundreds of new simulations are added each week.
We’re actively developing features that will allow you to search more quickly and easily for the simulation content you want. In a first step, new sorting mechanisms were added that allow the user to sort public projects by:
- # of views
- # of likes
- # of copies
- Creation date
- Modification date
Try them out in combination with the search field to see if there are other users working on applications similar to your own.
