ls-dyna_mpp_d_R12 error while loading shared libraries libmpioso1 cannot open shared object file No such file or directory

This error message indicates that the LS-DYNA program is unable to find the required shared library file "libmpio.so.1". This file is likely missing or not installed on your system.

To resolve this issue, you can try the following steps:

Check if the required library file is already installed on your system. You can do this by running the following command in a terminal:
```
$ locate libmpio.so.1
```
If the file is found, note down its path and set the LD_LIBRARY_PATH environment variable to include that path. For example:
```
$ export LD_LIBRARY_PATH=/path/to/libmpio.so.1:$LD_LIBRARY_PATH
```
If the required library file is not found, you will need to install it. The exact steps for installing the library may vary depending on your operating system and package manager. For example, on Ubuntu or Debian, you can install the library by running the following command:
```
$ sudo apt-get install libmpich-dev
```
On CentOS or Red Hat Enterprise Linux, you can install the library by running the following command:
```
$ sudo yum install mpich-libs
```
After installing the library, try running the LS-DYNA program again.
