Abaqus Input Format | Dassault Systemes | Data Files |
The INP file is the .INP extension format used by the Abaqus suite of engineering simulation tools. It is used to store the input parameters for analyses performed within the Abaqus suite, and also to store the resulting output. Features stored within an INP file can include commands and data related to geometry, objects, boundary conditions, disciplines such as structural analysis or fluid dynamics. Subsequent lines in an INP file will then contain further commands or objects related to computational steps and options.
Associated Software
The .INP file type is primarily associated with the Abaqus FEA software suite. It may also be seen in other software titles which are compatible with Abaqus formats, such as CivilFEM, ISIGHT and CADMould 3D+, although they are usually converted into proprietary file formats for use within these programs. The.INP file will also be used when plotting or printing results from various analyses run using Abaqus.
Other File Types
Similar file types related to studies conducted using the Abaqus suite include the .DAT, .PRT, .SIM, .ODB and .STA extensions. The DAT extension stores data collected during simulations or analyses in a tabular format, while PRT files are generated during post-processing steps such as creating colour plots of results. SIM files contain simulations setups, ODB files store generations of finite-element results, and STA files store time step data.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .INP) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .INP extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .INP file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .INP extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .INP extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .INP file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .INP file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .INP file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .INP file) will be extended to the maximum.
It is also good to check
- if the .INP file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
