## Stretching of a Thin Plate with a Hole

## Stretching of a Thin Plate with a Hole

This example is a well known benchmark test case from structural mechanics, a thin plate with a circular hole in the center is subjected to a load and stretched along the horizontal axis. The plate is thin enough to satisfy the two dimensional plane stress approximation, and since both the problem and solution will be …

## Axisymmetric Fluid Flow

## Axisymmetric Fluid Flow

FEATool is designed to be able to perform complex multiphysics simulations in arbitrary dimensions (1D, 2D, and 3D). However, running full 3D simulations often requires a significant amount of computational resources in the form of memory and simulation time. It is therefore desirable to find simplifications to reduce …

## Heat Exchanger

## Heat Exchanger

This heat exchanger example illustrates the multiphysics modeling capabilities of FEATool. The model consists of a series of heated pipes surrounded by a fluid at a lower temperature, and features effects of both free and forced convection. Two types of physical phenomena are considered, fluid flow which is modeled by …

## Poisson Equation with a Point Source

## Poisson Equation with a Point Source

The classic Poisson equation is one of the most fundamental partial differential equations (PDEs). Although one of the simplest equations, it is a very good model for the process of diffusion and comes up again and again in many applications such as in fluid flow, heat transfer, and chemical transport. This example …

## Wave Equation on a Circle

## Wave Equation on a Circle

This tutorial explains how to set up and solve a generalized wave equation model on a circle, like for example for a drum or membrane, and then tracks how the initial parabolic deformed state will affect the resulting shape. The wave equation is one of the classic hyperbolic partial differential equations (PDE) of the …
