![]() ![]() Now, if you want to know more about CAD formats, here’s another article in which I explain in more details the different CAD formats and how you should use them correctly for simulation. That’s because I think you have to “see” it in order to get it -) In this video, I explain how to construct a few simple mesh elements and how those are then translated into a text format inside a NASTRAN file. Here’s a video in which I explain how this kind of NASTRAN file is structured: It is currently possible to read a mesh exported to Abaqus’. This information is then stored in a class based format in Phon which is easy to query and modify the mesh. Nastran was the pioneer code invented by the NASA to analyze FEA models and so they built a standard of how this kind of text file should be written than is still used in many FEA software even now. Reading a mesh is in Phon the process of parsing a file containing nodes, elements, and eventual sets (element sets and node sets). This transfer of data is usually done using a text file formatted in a special way in order to convey those different data correctly. Then you need to send all those data to the solver which will interpret them and run them trough its algorithms to provide you with results. regasm Nastran file is a text file than contains the input data for a CAE simulation software that are formatted under a certain format called “Nastran format”.įor example, when you prepare an FEA model, you will: The following example registers the primary interop assembly. Regasm.exe adds an entry for the primary interop assembly under the same registry key as the original type library. In this command, assemblyname is the file name of the assembly that is registered. Use the Assembly Registration Tool (Regasm.exe) to register a primary interop assembly. You can avoid accidentally generating and using a new interop assembly if, at some time in the future, you do use Visual Studio to reference a type for which you have an unregistered primary interop assembly. Registration is the best way for you to locate a primary interop assembly on your computer. Likewise, the Type Library Importer (Tlbimp.exe) also uses the registry to locate primary interop assemblies.Īlthough it is not necessary to register primary interop assemblies unless you plan to use Visual Studio, registration provides two advantages:Ī registered primary interop assembly is clearly marked under the registry key of the original type library. If Visual Studio cannot locate the primary interop assembly associated with the type library, it prompts you to acquire it or offers to create an interop assembly instead. Visual Studio looks for and uses a primary interop assembly the first time that you reference a type from a COM type library. You must register all acquired primary interop assemblies on your development computer before you can reference them with Visual Studio. When your application requires such insulation, generate your own interop assembly instead of using the primary interop assembly. ![]() However, this strategy provides no insulation from changes a vendor might make to types defined in a primary interop assembly. In addition to providing guaranteed type compatibility, primary interop assemblies are often customized by the vendor to enhance interoperability.Įven if you do not plan to expose third-party COM types, using the primary interop assembly can ease the task of interoperating with COM components. If you plan to expose third-party COM types to other applications, always use the primary interop assembly provided by the same publisher as the type library it defines. The solution to this type incompatibility problem is for each developer to obtain the vendor-supplied and signed primary interop assembly. This plugin combines respectively ParaView’s scalability in parallel and Gmsh’s ability to apply h-refinement of the. ![]() Each time a developer imports and signs a COM type library, that developer creates a set of unique types that are incompatible with those imported and signed by another developer. In this context, a new ParaView plugin which integrates Gmsh as an external library has been implemented for off-line post-processing and visualization of high-order solutions saved under the Gmsh format, see Figure 1. NET Framework application can generate an interop assembly, doing so creates a problem. For information about overriding the class interface with an interface of your choice, see COM Callable Wrapper.Īlthough any developer who wants to use COM types from a. In some cases the interface used to marshal the class is known as the class interface. Classes can be marshalled only by COM interop and are always marshalled as interfaces. ![]()
