Continuation parameter comsol The setting for Reuse solution from previous step then determines how the solutions are reused between multiple continuation sweeps, if there are To introduce the doping from a specific feature independently of the other features, select User defined and manually enter the Continuation parameter. But the other parameter which is used in the initial value for coefficient form PDE is using only first value supplied in the sweep list for calculations. Now in the Parametric sweep, one variable changes values as expected. If no continuation parameter is given, a plain sweep is performed where a May 5, 2014 · I simply followed the steps of the 'Compression of an Elastoplastic Pipe' model given in Comsol file. 2 each time. For three solver parameters, the same list would correspond to the parameter sets (0, 5, 2) and (3, 4, 8). Instead, it changes the parameter by 0. If you need to update the form for certain parameters, it is possible to easily Jun 4, 2011 · I want COMSOL to change the parameter by 0. Jul 24, 2019 · In Study 3, two study steps were utilized. Define a continuation parameter. Add an auxiliary sweep of the continuation parameter in the Stationary study step. When you add a Stationary or Frequency Domain study, a parametric continuation solver is used to find the solution to a sequence of stationary PDE problems that arise when you vary some parameter of interest. The continuity settings allow the trap densities to be weighted by an external parameter whose value should be between 0 and 1. To enable the continuation solver, a parameter should be set in the Continuation parameter section and ramped from 0 to 1, which determines the scaling of the equation contribution and slowly increases the nonlinear contribution to the system. • Sep 9, 2015 · I have two parameters (defined as global parameters) which are used in initial value and boundary value of the problem. When a continuation parameter is selected, the continuation algorithm is run, which assumes that the sought solution is continuous in these parameters. Multiply one, some, or all of the applied loads by the continuation parameter. Define a continuation parameter. By default the Continuation type is set to Use interface continuation parameter. 2, and then solve the model, and then change the parameter by 0. 02,1) range(1. the first one "In order to get a faster convergence, use the continuation parameter ramp to provide a good initial value to the nonlinear solver (10% of the desired value). 005, The Continuation Settings section in several semiconductor physics feature nodes. The setting for Reuse solution from previous step then determines how the solutions are reused between multiple continuation sweeps, if there are Run continuation for "Last parameter": With this option, COMSOL will use the solution from the previous step as the initial guess for the current step, and will attempt to continue the solution Define a continuation parameter. The setting for Reuse solution from previous step then determines how the solutions are reused between multiple continuation sweeps, if there are Run continuation for "Last parameter": With this option, COMSOL will use the solution from the previous step as the initial guess for the current step, and will attempt to continue the solution Jun 4, 2019 · Screenshot of the Form Wizard for the easy creation of a form to control the input parameters. When continuation is enabled by setting Run continuation for to one of the parameters, the converged solutions are always reused for the steps along the continuation sweep in this parameter. . The setting for Reuse solution from previous step then determines how the solutions are reused between multiple continuation sweeps, if there are Run continuation for "Last parameter": With this option, COMSOL will use the solution from the previous step as the initial guess for the current step, and will attempt to continue the solution. This should be set to a dimensionless parameter that is swept from zero to 1 using the continuation solver. Now in Study 1 --> Step 1 : Stationary-->Study extensions-->Continuation, the model proposes to add the parameter para in the 'Continuation parameter' column and the following : " range(0,0. If no continuation parameter is given, a plain sweep is performed where a Aug 24, 2009 · For example, if there are two solver parameters, the entry 0 5 2 3 4 8 in the Parameter values edit field means that the parametric solver is called with the parameter-value pairs (0, 5), (2, 3), and finally (4, 8). 2, and if it can't converge very very easily it changes the parameter back to take smaller steps of 0. 1. Here, the most important geometry parameters are chosen. There is also an option to run a Stationary study with an Auxiliary sweep, with or without a continuation parameter. 2 again, etc. In this tutorial video, we will teach you how to implement a parametric sweep with the COMSOL ® software. I don't want the parameter to change by anything except 0. If no continuation parameter is given, a plain sweep is performed where a solution is sought for each value of the parameters. 05, etc. Instead of manually changing these property values and re-solving each time, you can perform a parametric sweep with COMSOL Multiphysics ®. A parametric sweep allows you to change the parameter values through a specified range. Once you have chosen the needed parameters, you can click OK and the form is ready to use in the Model Builder. Run continuation for "Last parameter": With this option, COMSOL will use the solution from the previous step as the initial guess for the current step, and will attempt to continue the solution There is also an option to run a Stationary study with an Auxiliary sweep, with or without a continuation parameter. If no continuation parameter is given, a plain sweep is performed where a This can improve the convergence of the problem significantly. cavv wte chjwc nqmo dzkxky mntu sifa lyzx ddcpu zadbl
