 +Note that [[en:computing:cluster:pripojeni:start|connection have to be opened with the X11 forwarding]] if you want to launch the **graphical interface** (Linux: ''ssh -Y''; Windows: active X server and //Enable X11 forwarding// in PuTTy). The graphical interface is slower than working on local machine due to network transfers. **Running the computations at the frontend node is prohibited**, use the scheduler Slurm.

-===== Running the program ===== 
  
-==== Interactive mode ==== 
  
-The //commands to start each environment are listed in the table above.// 
  
-ANSYS offers two environments to work in: 
-  * MAPDL -- the original working environment, started with the command  
- 
-  launchxxx 
- 
- 
-  * Workbench -- new environment, launched with the command  
- 
-  wbxxx 
- 
-Fluent is launched with the command 
- 
-  fluentxxx 
-   
-   
-Working in interactive mode directly on the servers is not very comfortable. Servers are primarily for computing and have little graphics power. It is preferable to prepare the task interactively on the PC and then run the calculation on the servers. The results can then be viewed again on the PC. 
- 
- 
-==== Batch execution ==== 
- 
-Documentation for batch mode is located in the program help in 
- 
-  ANSYS Documentation -> Mechanical APDL -> Operation Guide -> 3. Running the Mechanical APDL Program -> 3.4 Batch Mode 
-   
-The calculation is started with the command 
- 
-  ansysxxx -b -p productvar < inputname > outputname 2>&1 
- 
-If we want to run the calculation in the background, then with the command 
- 
-  nohup ansysxxx -b -n nnn -p productvar < inputname > outputname 2>&1 &  
-   
-where ''xxx'' corresponds to the version (172, 190, 193, 201), ''nnn'' is the number of cores used (max 16) and ''productvar'' specifies the license used. The values are given in the following table. If the license is not directly specified, Academic Teaching is used. 
- 
-^ productvar ^ license ^ 
-| ''aa_t_a'' | Academic Teaching | 
-|'' aa_r'' | Academic Research | 
- 
-If the ''ansysxxx'' command doesn't work (no link is created in ''/usr/local/bin)'', you need to write out the full path 
-   
-  /ansys_inc/vxxx/ansys/bin/ansysxxx -b -p productvar < inputname > outputname 2>&1
