How to open OP4 file?
The main problem with Nastran Output is that the OP4 file is incorrectly associated with programs. This causes the file OP4 to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.
The first thing you should do is just "doubleclick" on the OP4 file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.
Step 1. Install MSC Nastran
An often overlooked issue is to make sure that MSC Nastran is installed on the computer. The easiest method is to use the system search engine by entering the program name MSC Nastran in it. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support OP4 files.
Programs to open OP4 file
Remember to download programs supporting OP4 files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of MSC Nastran with OP4 files
If the application is or has been freshly installed, but the OP4 file still does not use the MSC Nastran program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. Checking the "Always use the selected program ..." box will permanently associate the OP4 file with the MSC Nastran program.
Step 3. Update MSC Nastran to the latest version
The fault may also lie with the MSC Nastran program, it is possible that Nastran Output requires a newer version of the program. This can be done using the application (if it provides such options) or from the MSC Software Corporation website and install the latest version.
Step 4. Check for the following problems with the OP4 file
If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:
The OP4 file may be unusually small compared to the original file. Usually this applies to OP4 files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our OP4 file. As a result of the scan, sometimes it is not possible to recover OP4 files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the OP4 files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular OP4 file corruption. You can restore the file from a backup or use MSC Software Corporation help.
The program indicates that the file is encrypted or corrupted. The encrypted OP4 files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. These directories are write-protected to them and it's very hard to fix this problem. It is best to move OP4 to a different directory.
This can happen on a file that does not support multiple access. Some file types can only be opened in one program at a time. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the OP4 file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
