Response

Solution > Result > Right click > Response

Introduction

Response is either a result component of solution or component like volume, mass, centre of gravity, and moment of inertia. It is used to query the component in selected entities.

Features

  1. Right click the results of solution to select the result component.
  2. Export Responses option is available at right click of Solution name to export the evaluated reponses.
  3. Only the valid result component will be listed based on the analysis type.
  4. In case when the result is already available the response value will be updated with the result value. If result is not available, the response will be updated once the result is available.
  5. Response can be defined for the following inputs,
    • Co-ordinate system
    • Entities
      • Body
      • Face
      • Edge
      • Vertex
      • Node
      • Element
    • Sets
    • Regions
      • RegionsBox
      • Cylinder
      • Sphere
      • Point
  6. We can compute the maximum and minimum result value over time / frequency and the time / frequency where the result is maximum and minimum for transient results. This option will be shown only for transient and frequency analysis types.
    • Plot Graph option is supported in right click options for responses when minimum or maximum value is requested.

Responses for Flow solution

Response for result components of flow boundaries/surface are supported for steady and transient flow solution.

Result components are:

  1. Mass flow rate
  2. Total Heat flow rate
  3. Total pressure
  4. Uniformity index – pressure
  5. Uniformity index –temperature
  6. Uniformity index – velocity (X, Y, Z)
Note:
  • For mass flow rate and total heat flow rate, user can either select the faces from GUI or select the flow boundaries/surface outputs.
  • If user selects the faces, SimLab computes the total heat flow rate and mass flow rate by Gaussian surface integration.
    • Heat flow rate is computed by

    • Mass flow rate is computed by

Computation of total heat flow rate and mass flow rate for shared faces
  • If user selects the flow boundaries/surface outputs, then acutrans is used to get the output value. If the input surface are shared faces between bodies, then this approach fails to compute the response.
  • Alternatively, SimLab-native computation approach can used for shared faces and the reference body can be specified to determine the directional heat flow or mass flow rate with reference to that body.
  • If the computed value is negative, the heat/mass flow flows into the reference body.
  • Eg: Shown below is water flowing inside the pipe made of stainless steel from two inlets, small and large inlets with velocity of 1.2 m/s at temperature of 320 K and 0.4 m/s at 295 K respectively. To see how heat flow flows across the solid-fluid interface, the total heat flow rate responses is created by selecting the shared faces along with a reference body.

Responses for electronics thermal solution

Temperature is a significant factor in electronic systems, affecting various components' behaviour. Temperature can influence the electrical characteristics of components and materials, leading to changes in resistance, conductivity, and other properties. Users can create responses for the temperature of one or any number of components to check its trend in the design of experiments.

Responses for electromagnetics solution

Various output parameters in electromagnetic solutions are of interest depending on the specific problem and application. SimLab allows the creation of responses for any of those parameters and DOE enables to analyse these output parameters under various working conditions.

Creating response for CAD-based solution

Response can be created by selecting the CAD body/face/face group for the following CAD-based solutions.
  • Drop test solution using Radioss solver.
  • 2D Electromagnetic solution.
  • Electronics thermal solution.
