Copyright Flomerics © 1 EFD Tips and Tricks Document Introduction This document was created to provide new users of EFD.Pro with useful tips and tricks for the software with the aim of maximising productivity. The information has been put together based on frequently asked questions and enquiries to the support team. For further help, please contact support@flomerics.co.uk Contents 1.

Showing / Checking Mesh There are 3 ways of checking and looking at the mesh of the analysis. Before this can be done, the mesh viewing option must be activated within EFD.Pro. To do this, navigate to: Flow Analysis » Tools » Options. The “Display Mesh” option checkbox under general options must be then checked. The mesh must already be generated by running the case with the solver option unchecked. 1.1 3D Mesh View Right click under the results tree and select “3D View”. The following dialogue box appears which can then be used to view specific types of cell. 1.2 Cut Plot Right Click under the results tree and select “insert”. Reference the cut plot using a datum plane and then ensure the “Mesh” option is checked. Using the preview option, the plane can be moved through the domain to look at the mesh. Once satisfied with the position, click “OK” to place the cut plot. Copyright Flomerics © 3 1.3 Surface Plot Right click under the results tree and select “insert”. Either select specific surfaces in the model to superimpose the mesh onto or use the “Use all faces” option. Ensure the “Mesh” box is ticked and then click “OK”. 2. Loading a Results File In a normal situation, once the solver has finished, the results file will be loaded in automatically so the post processing can commence. If EFD.Pro has been closed and reopened, the results file is not accessible straight away and needs to be loaded in. To do this, open the EFD.Pro instance in Pro/ENGINEER and go to the EFD tab ( ). Right click and select “Load results”. A dialogue box will appear prompting a file to load. The box on the right of the screen displays EFD.Pro information about the selected file. 2.1 File Types .cpt Mesh File .fld Results File – characterised by iteration count r_000000.fld Results file after 1 iteration – Used as a backup Copyright Flomerics © 4 3. Check Geometry Before an EFD.Pro analysis can be run, the geometry must be checked for modelling errors. Parts can be assembled in CAD in a way which is not possible in reality and when this occurs, EFD.Pro cannot mesh the model. A specific example is invalid contact. An invalid contact will exist if two solid bodies intersect and the intersection area is equal to zero (i.e., a line contact or a point contact). Examples of invalid contact are shown in the diagram below. To check for this in the assembly, please use the inbuilt checking function using: Flow Analysis » Tools » Check Geometry Ensure the “Check for invalid contact” box is checked and click the “Check” button. Any errors found in the assembly will be highlighted in the bottom of the window. EFD.Pro will indicate between which parts the invalid contact is occurring so the geometry can be rectified by: suppressing, deleting or moving parts to eliminate the invalid contact. Once all the errors have been fixed, press the “Check” button to ensure you are getting finite numbers in the Fluid Volume and Solid Volume readout. 4. Support Function If you are experiencing issues with the operation of EFD.Pro, there is a built in function to send your model to the Flomerics support team. Please use this feature by navigating to: Flow Analysis » Tools » Support Service There is a wizard which will guide you through the steps required for the support service and at the end there is an option for which files to attach. All geometry will be attached by default and normally, no results files will be required (due to their large size). All of the parts and EFD.Pro setup files will then be zipped up into a FWARC file which can then be emailed to support@flomerics.co.uk Copyright Flomerics © 5 5. Documentation Location The Tutorial, Fundamentals and Users guide for EFD.Pro is available in electronic format and can be found under: Start » Programs » EFD.Pro » English documentation These documents outline many of the concepts and fundamentals of EFD.Pro and should be consulted if you are unsure of how to apply some of the features of EFD.Pro. The help function is also very useful for general EFD.Pro help and can be found in: Help » EFD.Pro Help Topics under the standard Pro/ENGINEER toolbar. 6. Freeing a Pro/ENGINEER license during solve Under normal situations, once the Run button has been clicked, Pro/ENGINEER does not close and continues to run in the background whilst the solver is running. It can be beneficial to close Pro/ENGINEER whilst the solver is running to free a license and also the RAM associated with Pro/ENGINEER. To achieve this, navigate to: Flow Analysis » Solve » Run The following familiar window appears: In the “Standalone or remote calculation” please use the pull-down list to select your machine name (RICHARDO-LAPTOP in my case) and then check the “Close Application” check box. The “Run” button can then be clicked as usual. Once the mesh generator has finished and Pro/ENGINEER has transferred all data to the solver, Pro/ENGINEER will then terminate without prompting so please ensure all work is saved. Copyright Flomerics © 6 7. Deleting an EFD Instance If an EFD.Pro instance is no longer required and needs to be disassociated from the geometry, the following steps should be followed. 1 Open the assembly and select “The Generic” instance which should always be at the top of the instance window. 2 Navigate to the family table under: Tools » Family Table 3 Highlight the EFD.Pro instance, right click and select “delete row”. 4 Click “OK” to exit the family table. 5 The associated NIKA directory in the working directory can now be deleted manually using windows explorer. 8. Disabling Components There are several benefits of disabling a component in EFD.Pro. A disabled component can be used to: Apply a local initial mesh Apply an initial condition Apply a rotating region Apply a porous medium Apply surface or volume goal to Post process a specific surface or volume in the flow domain A disabled component is not taken into account in the meshing process and therefore is not used in the solver. To check the status of a component, navigate to: Flow analysis » Component Control Any component which has a white icon is disabled. When applying a rotating region or porous medium, the component is disabled by default.
