# How can I speed up my CST simulation?

## How can I speed up my CST simulation?

Using Hardware Acceleration to Speed Up Simulations For select solvers in CST Studio Suite, GPU can be used to speed up the simulation even more compared to using CPU. This is because GPUs have many processing units, or cores, which are very efficient in performing calculations when used in parallel.

## How do you reduce the number of mesh cells in CST?

u can change from home page of CST go to Mesh tool then global properties then increase the (Near of model). Steps per wavelength: This value is connected to the wavelength of the highest frequency set for the simulation. It defines the minimum number of mesh cells that are used for a distance equal to this wavelength.

**What is S parameter balance CST?**

S-Parameter Balance. The S-parameter balance is calculated as the square root of the summed power leaving the structure through all ports. The balance should be one for structures that are loss-free (no material losses, no lumped element R) and closed (no open or lossy boundary condition).

**How do you change the frequency range of CST?**

Change Fmin and Fmax to the desired values in the frequency range settings dialog box (opened by pressing the “Frequency range” icon or choosing Solve ⇨ Frequency) and store these settings by pressing the OK button.

### What is a frequency domain solver?

Frequency domain solvers uses FEM (finite element method) to solve the maxwell’s equation. The two solvers uses two different methods to solve the same problem. Frequency domain solvers are useful for smaller structures like unit cells and FSS. Floquet analysis can be done using frequency domain solver.

### What is mesh CST?

This is probably the most effective way of working with CST STUDIO SUITE. The mesh generator determines the important features of your structure and automatically creates a mesh, which represents your structure and the fields equally well. This means that the frequency range and dielectrics, metallic edges, etc.

**What do S parameters mean?**

Scattering parameters or S-parameters (the elements of a scattering matrix or S-matrix) describe the electrical behavior of linear electrical networks when undergoing various steady state stimuli by electrical signals.

**What is S parameter in antenna?**

Antennas. S-parameters describe the input-output relationship between ports (or terminals) in an electrical system. For instance, if we have 2 ports (intelligently called Port 1 and Port 2), then S12 represents the power transferred from Port 2 to Port 1.

#### What is automatic optimization?

Automatic optimization is a set of optimization rules that includes a frequency cap, and examines all the ads within your campaign by CPA (cost per action). Based on CPA, automatic optimization pauses under-performing ads and allocates budget to the best ads within the campaign.

#### Which is a time domain signal in CST MWS?

excitation itself is a time domain signal, typically a Gaussian pulse. In CST MWS, the. width of the excitation signal is automatically adjusted to contain the desired spectral. content of interest given by the frequency range specified by the user.

**Which is the best meshing mode for CST?**

CST provides four meshing modes. For simplicity, start with the PBA mode and later move to the EFPBA mode if the mesh density becomes very high (> 100 lines per wavelength).

**How are models parameterized in CST Studio suite?**

CST Studio Suite models can be parameterized with respect to their geometrical dimensions or material properties. This enables users to study the behavior of a device as its properties change. Users can find the optimum design parameters to achieve a given effect or fulfill a certain goal.
