Hello everyone I have a question about Comsol software. I use a time-dependent study and I want to divide my interval so that I see the results every five seconds and if they are correct, I give the last interval value to the first value of the next interval to the extent that simulation is performed for the entire time interval. In addition, since I use the university's fast processing center systems, I want to run only a new period each time so that I do not have to pay extra. Is this possible?
Hello
Have a good time.
Yes, it is possible.
You can proceed according to the attached file.
If you have a problem, I am at your service.
Erfan Rahimi Hello, Thanks a lot but that's not what I meant, I wanted to use the result of one interval for the next interval
Hello Shadi Sarrami,
Have a great time!
1:Time-Dependent: Study is used when field variables change over time.
In electromagnetics, it is used to compute transient electromagnetic fields, including electromagnetic wave propagation in the time domain. In heat transfer, it is used to compute temperature changes over time. In solid mechanics, it is used to compute the time-varying deformation and motion of solids subject to transient loads. In acoustics, it is used to compute the time-varying propagation of pressure waves. In fluid flow, it is used to compute unsteady flow and pressure fields. In chemical species transport, it is used to compute chemical composition over time. In chemical reactions, it is used to compute the reaction kinetics and the chemical composition of a reacting system.
2-Time-Dependent, Modal: Study is used to compute the dynamic structural deformation of an object subject to a transient force.
The study consists of two study steps: one study step for computing the eigenfrequencies and eigenmodes of the structure, and a second study step for computing the modal response. In the modal superposition analysis, the deformation of the structure is represented by a linear combination of the structure's eigenmodes. This means that the frequency content of the loads is limited by the frequencies of the computed eigenmodes. All loads are assumed to have the same variation with time. A Time-Dependent Modal study usually results in a faster computation than a direct solution using the Time-Dependent study.
3-Time Dependent, Prestressed, Modal: Modal study is used to compute the response to time-dependent loads fluctuating around a prior static load. The solution is performed using modal superposition.
The study consists of three study steps: a Stationary study step followed by an Eigenfrequency study step and a Time-Dependent, Modal study step.
4-Time Dependent Study via a Reduced-Order Model: Using modal superposition.
The study is an entry point to facilitate the setup of a reduced-order model and to perform a transient analysis. When selected, several studies will be added together with a node under Definitions for prescribing the reduced-order model input.
