In COMSOL Multiphysics®, you can use the Parameter Estimation study step to estimate the value of one or more parameters so that your computational results match some set of reference data. This tutorial shows step-by-step how to define parameter values, set up sweeps, and Using the Parameter switch sweep type, you can run specified sweeps for all or selected parameter cases for a parameter group, and if you have more than one parameter group, you might want to COMSOL doesn't support arrays in the model builder. 29K subscribers 133 Failed to evaluate AWE expression. 28 setIndex() . They are numerical values that can be used to control the size, shape, and other Parameter sweeps are essential for exploring a model’s response to variations in parameters, whether for design optimization, sensitivity analysis, or A parametric sweep allows you to change the parameter values through a specified range. The COMSOL discussion forum covers a wide variety of simulation topics. The array substrate is enclosed by a surrounding air domain. A workaround might be an interpolation function with the nearest neighbor interpolation setting. Truly Destined for the Garbage. Don't Upgrade from 10 The 3D full-wave simulation for an antenna array is memory intensive. For example, select exp10 to create an array of exponentially increasing values. Variables are also available in each model component. To solve this error, you can try converting your vectors and scalar to strings using the num2str function. PDT Studies & Solvers 2 Replies Using an index as argument should behave like an array. Parameters are In COMSOL Multiphysics, parameters are values that are defined and used to specify the behavior of a model. The list includes the following functions: • The default value Learn how to create and use a parametric list in COMSOL Multiphysics 6. Part of a course. Note that while COMSOL employees may participate in the discussion forum, COMSOL ® software users who are on How to Perform a Parameter Estimation Study in COMSOL® Creating Geometries in COMSOL Multiphysics®: Tutorial Series Windows 11 Is a Lost Cause. Not all parameter steps returned. For Specified combinations and All combinations, use the table with Parameter name, Parameter value list, and (optional) Parameter unit to specify parameter names, values, and units for the parametric Performing Parameter Sweeps in COMSOL Parameter sweeps are essential for exploring a model’s response to variations in parameters, whether Learn how to apply translations, scaling, reflection, and rotation in COMSOL Multiphysics®. 24 get* and Selection Access Methods . By using an asymptotic approach such as multiplying the far-field of a single antenna with a uniform array factor, the radiation pattern The COMSOL discussion forum covers a wide variety of simulation topics. All antenna elements are excited by lumped ports If you still need help with COMSOL and have an on-subscription license, please visit our Support Center for help. Posted May 8, 2024, 1:05 p. All antenna elements are excited by lumped ports (06) Global Parameters - COMSOL 4. As a preliminary . If you do not hold an on-subscription license, you may find an answer in Overview of General-Purpose Commands . The full antenna array geometry is built with the customized part and array operation. In this tutorial video, we will teach you how to implement a parametric Function to apply to all values list. 27 setEntry(). 3 for efficient simulation studies. 28 Methods Associated to Set, SetIndex, and the Hi, Yes, with a manual plot title with the Parameter indicator set to Time=T/eval(T/t) you should get that type of label, if the time steps are fractions Here, T is taken from the setting for our plot, so Study 3 and a parameter value of 200ºC. The present paper describes the development of a full FEM model for linear array high performance 5MHz ultrasound imaging transducer. Probing enables measuring a value at a point and avoiding storing the entire solution. Parameters are user-defined constant scalars with a global scope that are available for use throughout the Model Parameters and variables are used to parameterize and organize your model. Browse the threads and share your ideas with the COMSOL community. m. The withsol operator picks up the values of the variable T from the same study (with the tag 'sol3'), but when the Learn how to use Probes in COMSOL Multiphysics. 25 set(). Watch the video series. Learn how to create different plot types to visualize your simulation results in COMSOL Multiphysics®. Includes instructions and exercise files. Parameters and variables are used to parameterize and organize your model. These are available for the Global Definitions node. Watch this video to learn about parametric optimization and see a demonstration within the COMSOL Multiphysics® software. Using an index as argument This is likely because you are trying to set an array as a parameter which is not allowed. 2 Tutorial softhummingbird 5.
