****************************************************************************** * Argus ONE - Plug In Extension, Release 1.0 * * Copyright 1997-1999 Argus Holdings Ltd. All rights reserved. * ****************************************************************************** The VirtualNodes PIE Purpose: The VirtualNodes PIE allows users of the Quad and Tri finite element modules to export 6 node triangular elements, and 8 and 9 node quadrilateral elements. Using this PIE users can export 6, 8 and 9 node FEM topologies and also evaluate node values at these extra nodes. Price: Free of charge to users of Argus Open Numerical Environments. Facts: The VirtualNodes PIE defines arrays in which the mesh topology is stored and reorganized and from which the extra nodes numbers, connectivities and locations are read by export templates. The PIE comes with 3 example export templates (for 6, 8 and 9 FEMs). The source code is also available for anyone who wants to change, enhance or use it for other purposes. Examples of templates --------------------- Three example export template files are available: - Tri6Mesh.met - A ready made export template that uses the PIE to export 6 node Triangular elements. - Quad8Mesh.met - A ready made export template that uses the PIE to export 8 node quadrilateral elements. - Quad9Mesh.met - A ready made export template that uses the PIE to export 9 node quadrilateral elements. Supported platforms ------------------- The VirtualNodes PIE is supported on MS Windows, PowerMac and SGI. The PIE was develope using the ArgusONE PIE technology and C++. Availability ------------ The PIE is currently available (free of charge) from the Argus ftp site at the following addresses: - MS Windows: ftp://ftp.argusint.com/pub/ArgusPIEs/PC_PIEs/Virtual_Nodes/ - SGI: ftp://ftp.argusint.com/pub/ArgusPIEs/SGI_PIEs/Virtual_Nodes/ - PowerMac: ftp://ftp.argusint.com/pub/ArgusPIEs/PPC_MAC_PIEs/Virtual_Nodes/ The .zip (PC) and .sea.hqx (PPC Mac) files include the full PIE with source codes. The VirtualNodes.dll is the file that you need to download to use the PIE on the PC. IMPORTANT NOTE: The following three files must be downloaded as ASCII files. The VirtualNode PIE PPC is the file that you need to download to use the PIE on the PPC Mac . The VirtualNodesPIE.so is the file that you need to download to use the PIE on the SGI. The Tri6Mesh.met, Quad8Mesh.met, and Quad9Mesh.met files are the example templates. Installing and usingthe VirtualNodes PIE ---------------------------------------- 1. Place the VirtualNodes PIE in the ArgusPIE directory. 2. If ArgusONE was running at the time you placed the PIE in the ArgusPIE directory you need to quit ArgusONE and run it again. 3. As long as this PIE remains in the ArgusPIE directory it will be automatically loaded each time you run ArgusONE. 4. In a mesh layer, from the File Menu select Rxport->Edit template 5. Use the Load button to laod one of the three supplied templates. 6. Use the Export by Template to export your mensh with the additionla nodes. Availability of source code --------------------------- The source codes are available from the ftp site. Warranty -------- This software is provided as a service to Argus Open Numerical Environments users.
