Heat dissipation of a LED with radial heat sink. Steady state Solid Heat transfer simulation to find out the Maximum temperature on the heat sink and LED source. Transient Heat transfer simulation to measure the time taken for the LED to heat up to the maximum temperature.

Example project of a multiphysics application. A Static and a Frequency analyses are used to determine the structural behavior of the assembly. Then, a conjugate heat transfer analysis will determine the thermal behavior of the cooling process of the motor - Copy

Analysis Type: Incompressible, Steady state analysis

This project aims at analyzing and understanding how thermal comfort can be achieved in an office space of 4 occupants.
The scenario takes place in summer conditions ( 42C outside temperature and  65 relative humidity). The thermal comfort metric used in this project is predicted mean vote (PMV) and the target range is -0.5/0.5.
The original scenario results, where the external walls have a low insulation value and the inlet temperature is 19.85 degrees Celsius,  show exceeding PMV values (2.8 on average at the humans' surfaces) that are beyond the recommended ASHRAE-55-2017 values.
To improve the PMV values and the energy consumed in order to cool the occupants, the insulation value for the walls and windows were changed to reflect the impact of adding an insulation layer. The results of the improved scenario show a significant saving in energy spending whereas the thermal comfort of the occupant isn't changed significantly. 
The next stage is to adjust and find an inlet temperature at a suitable level in order for the occupants to feel comfortable. The flowrate value wasn't modified because it would produce airspeed and therefore negatively impact the PMV values.
Working with a difference between the average room air temperature and the inlet temperature of 9 degrees Celsius, and aiming for a 22degres Celsius average room temperature as a starting point, an inlet of 14 degrees was used.
Simulation runs were performed at 14,13,12,11, and 10 deg Celsius until the measured PMV values for the occupants were all within the target range of (0.5/0.5). The  satisfactory condition scenario was determined to be with a 10 degrees Celsius inlet temperature.

This project analyses the dynamic impact stresses and deformation exerted on a pair of headphones that have been dropped from head height. A geometry change has been made after reviewing the max stresses in order to mitigate the risk of breakage.

Project goal: Try the simscale solution for modal frequency analysis

In this project a multiphase flow simulation of a stirred reactor is demonstrated.

The purpose of this project is to use experimental results from the Architectural Institute of Japan to validate CFD results gained from SimScale. The case being validated is Case E, which consists a complex of buildings with simplified geometry. Many scenarios are presented in Case E, The scenarios used to validate the SimScale platform were the North, East, South and Westerly winds for the after construction scenario.

The SimScale CFD results were compared to the experimental results and found to have good correlation. Some underprediction was seen in the k-epsilon models in the strong wind regions and underprediction in the wake regions, but is a known trait of the K-epsilon model and is acceptable and should be considered when evaluating results.

Tutorial project for a flow analysis of a pipe junction. The project only provides the geometry to start with. See our tutorials section to have a look at the step-by-step instructions to set up the simulation.

An electric soldering Gun is to be powered by an oscillating current. An oscillating heat generation is applied to the tip of the model to simulate this power cycle.

Agenda is to perform time-varying Heat Transfer analysis and examine the temperature distribution.

The purpose of this project is to use experimental results from the Architectural Institute of Japan to validate CFD results gained from SimScale. The case being validated is Case D, which consists of a single high-rise building, surrounded by blocks of simplified buildings. The geometry used was the scaled geometry from the data file provided by the Architectural Institute of Japan, and measurements were taken at points also listed in the data file.
