APDL is commonly used to automate the task or even make a complete parametric model. It comprises of a wide array of different features such as matrix and vector operations, do-loop and if-then-else functions. ANSYS APDL is a time-tested old-fashioned command-driven program that allows the user to input line by line codes one at a time and execute them on demand. Using APDL instead of the modern user-interface is said to give the users more power and control over each step of their simulation. In the past, there used to be more than ten processors, but now most of them have been undocumented. The commands that the users use are at times dedicated to one processor only.

APDL is commonly used to automate the task or even make a complete parametric model. It comprises of a wide array of different features such as matrix and vector operations, do-loop and if-then-else functions. ANSYS APDL is a time-tested old-fashioned command-driven program that allows the user to input line by line codes one at a time and execute them on demand.
Using APDL instead of the modern user-interface is said to give the users more power and control over each step of their simulation. In the past, there used to be more than ten processors, but now most of them have been undocumented. The commands that the users use are at times dedicated to one processor only. In the case where you input a preprocessor command when you are in the postprocessor section, the system will generate an error. Regardless of where you are in the model tree of your project, if you need to go from your current processor to another processor, you just need to insert the proper set of commands to change the processors.
The following are the processor types and their respective commands. This processor comprises of all the design modification and changes that need to be done to your geometry.
This is the most visited processor in product design and testing. The post-processor allows the users to work with their results, makes graphical outputs, and do in-depth post-processing.
This command is seldom used as the users are already in this processor while working on their product. This processor enables the users to change elements, create things, or modify the meshing according to the requirements. The users usually go to this processor only when they require the name changing or changes to the file properties.
This command is a way to interrogate your model with all sorts of the useful information such as the largest Y value for node position, number of nodes, loads on a particular node and the information on results. Named selection is the group of entities such as the edges, vertices, and elements that are grouped so that the user can scope on them rather than selecting each function individually. All the nodes that are in contact with the Named selection are converted into components.
The user can also create their own nodes and elements. The users must give it a unique name and operate it away. The jobname is the name of your solver job. In some cases, the users may want to write out specific information on the output file. This list is certainly not a definitive list of important commands for APDL. The key to using APDL is to know the fact that commands are your friend for this software, and you should learn how to implement these commands for your own benefit.
The following are some of the reasons why many professionals still prefer APDL over other solver systems. More command and control at each step The current solving methods and the modern GUI allows the user to select from preset options and have limited selections. Using presets and templates causes the users to lose control over the design and simulation in some cases.
Though the loss of command is quite unnoticeable for most of the users, but for in-depth simulators, they need more control at each step of their simulation. Better suited for programmers In some cases, the user carrying out the simulations are good in programming and much more efficient in coding than navigating a complex GUI.
For such users, who are fluent in coding and prefer the keyboard to write the commands rather than click here and there, the ANSYS APDL serves as a good platform to carry out their simulations. Faster and efficient Though ANSYS has worked hard to make the user interface as efficient and streamline as possible, no user interface can beat the power of direct coding to carry out the commands and the functions.
Navigating to different panels and sections to do one part of the simulation is comparatively slower than just opening the APDL window and typing in the command.
Troubleshooting is easier Troubleshooting via APDL window is comparatively easy if the user knows how to read the error reports. The conventional user interfaces simple states the error, whereas, in APDL, the user can directly work with the lines of code to see the error and work out the solution on the spot.

But that may not be the best for your model. Note: The new element must have the same topology. But if the node ordering is the same the topology then you can make that change using the ET command. This is the fastest way to change an elements definition.
