Jul 29, 2017 Hi, If u have done a basic coursework on FEM it would be really nice, even if you have not done than it's not a much problem. Dyna itself is capable of everything and u need have basic elementary knowledge of physics that's it. You can directly.

1. Software Products and Documentation
These are the LSTC software products and documentation available for download from this site.
Each of these components must be downloaded and installed separately. LSTC provides highly-optimized versions of LS-DYNA, tuned for a large variety of hardware and operating systems. For this reason, many builds of LS-DYNA function correctly only for a narrow range of hardware and OS. So it is critically important that users download a build of LS-DYNA which most closely matches their own hardware/OS combination.
2. Product Licensing (Network and Node-Locked)
LS-DYNA is licensed according to how many cores on which the software may run at once. For example, an 8-core license allows any of the following scenarios (and more):
Licensing schemes for LS-DYNA:
LS-PrePost, LS-OPT, and LS-TaSC do not require runtime licenses for use by LSTC customers. All LSTC customers may download, install, and run these programs without charge. No license key is required. These products are actively developed and maintained by LSTC.
License HOWTO Documents
3. Configuring LS-DYNA to Access LicensesAccessing Network Licenses under Unix/Linux/SolarisEnvironment Variable Settings
LS-DYNA can obtain a network license from an LSTC License Server using environment variables. Environment variables are specified in different ways, depending on the user logon shell:
To use a network license only, set the environment variable LSTC_LICENSE to 'network'
You must also specify the host or IP address of the machine where the license server is running using the LSTC_LICENSE_SERVER environment variable. The proper setting of this variable depends on whether or not you are using the default port for the license server, and whether you are using a single license server, or a redundant triad server.
Single quotes are required for redundant servers in order to avoid misinterpretation of parentheses. There are other methods for specifying the license server, but setting these environment variables overrides all other methods.
LSTC_FILE License File Directives
LS-DYNA can read server information from a file named LSTC_FILE. The best way to do this is to create/edit a file named LSTC_FILE in the same directory as the LS-DYNA executable. Add these lines to LSTC_FILE
DO NOT enclose host_or_ip with single quotes. As in the case of ENVIRONMENT VARIABLES (above), there are four possible ways to specify '#LICENSE_SERVER'. The '#' character must appear in the first column of the line, with no space between '#' and LICENSE_TYPE or LICENSE_SERVER. The effect of these lines is the same as setting the environment variables
Keep in mind that you can override any settings found in LSTC_FILE by directly setting the environment variables LSTC_LICENSE and LSTC_LICENSE_SERVER. This is useful to know in cases where LSTC_FILE contains incorrect information, but you cannot change the file because of permission issues.
WARNING: Some text editors do not automatically create files with complete lines. Use 'vi LSTC_FILE' to check this. If you see [noeol] at the bottom of the vi window, then there is no final end-of-line character in the file. If that happens, then type ':wq' in vi to write the file and quit. Vi will add the proper eol character.
NOTE: If LSTC_FILE is found in '/usr/local/lstc', then that file will be used instead, regardless of whether or not a file named LSTC_FILE is found with the LS-DYNA executable. We no longer recommend placing LSTC_FILE in '/usr/local/lstc'.
NOTE: If the LSTC_FILE environment variable is set to a file name, then $LSTC_FILE is used instead of any file named LSTC_FILE found with the LS-DYNA executable. We recommend that you not set the LSTC_FILE environment variable, unless absolutely necessary.
Setting the LSTC_FILE environment variable may be necessary if, for some reason, LSTC_FILE cannot be found when placed with the executable. Then you must set the LSTC_FILE environment variable to the absolute pathname of the file LSTC_FILE. This should not happen under ordinary circumstances.
Accessing Network Licenses under Microsoft Windows
The general format for the Network License Manager field varies according to the type of server configuration you have:
Accessing Node-Locked Licenses under Unix/Linux/Solaris
If LS-DYNA uses a node-locked license, then LS-DYNA must be able to locate the node-locked license file. LS-DYNA looks for a license file in the following locations, and in the specified order:
