In case of structural failure, Finite Element Analysis FEA may be used to help determine the design modifications to meet the new condition. However, it is also routinely used in the analysis of many other types of problems, including those in heat transfer, fluid dynamics and electromagnetism. FEA is able to handle complex systems that defy closed-form analytical solutions. Originally for CFD only, but now includes finite element analysis through tetrahedral decomposition of arbitrary grids.

FEMtools, Dynamic Design Solutions: A toolbox for static and dynamic simulation, verification, validation and updating of finite element models. Includes also modules for structural optimization and for obtaining experimental reference data. Marketed as Straus7 in Europe. The important feature of the system is its close relationship with the well-known system of designing, i.

Additionally, the graphical display and reporting of loads have been further improved to support model verification and the large number of load cases.

The latest release comes with several updates to the code check to further automate this process. Find out more Get in touch with us or sign up for events and training.

In the Edit Beams dialog go to the Offset Vector tab and flush the whole beam at top.

Copy this quarter by mirroring it about origin in X-direction. Go to the Mirror tab and enter data as shown below. The Preview check box verifies the position of the copy before executing the operation. These are surfaces in the mirror plane and copies would come on top of the originals which cannot be accepted.

Click OK to the warning. Again click OK to the warning about surfaces that cannot be copied. These are modelled as beam elements with section Pipe1 and material Steel. Steel will be the material to use for the remaining structure so this material may as well be set as default. The braces connect with the columns at the top of the conical transition as show below. The name of the exported file should be T2. For meshing the braces no mesh density is required the minimum default density will give two beams.

Use the sections Pipe2 and Pipe3 and follow the guidance on the next page El. Continue by the sloping legs. These beams may be copied by mirroring or you may find it more convenient to create them in a more direct manner. All with section Pipe3 except for the four short top horizontal beams at elevation 65 that are Pipe2.

This facilitates X: Note that the Default display configuration displays the compartments in a brownish colour. Also note that clicking the plate selection button , i. Furthermore, these load cases should be numbered consecutively after the dummy hydro pressure load case for the outer water pressure in this workshop: load case 1, LC1. Do not check Dummy Hydro Pressure. Select a compartment and right-click it in the browser to open the Properties dialog.

Select Dummy Hydro Pressure from the pull- down menu as shown to the right and click OK to accept the data and close the dialog. After this you should see orange load arrows as shown to the right using Modelling - Transparent display configuration for each compartment load case. The lower figure shows the equipment in the positive X-Y quadrant. The exact position of the equipment in this quadrant is 20,20, Right-clicking an equipment and selecting Properties allows such exact positioning.

Each copy must be positioned exactly. Such mass will be independent of the load cases, yet we must position the equipments within a load case and thereafter select to represent the equipment as load case independent mass. Let us use the last compartment load case LC5 for the equipments.
