Dear friend,

To consider the stress and displacement obtained from the first simulation in the second one, you should use the study: Prestressed Analysis, Eigenfrequency/ Prestressed Analysis, Frequency Domain. Please check the attached file.

As described by Comsol, the Prestressed Analysis, Eigenfrequency study is used to compute eigenfrequencies and eigenmodes that are influenced by a prior static load. The study consists of two study steps: a Stationary study step followed by an Eigenfrequency study step. The study computes the eigenfrequencies and the shapes of the eigenmodes when influenced by a prior static load on the structure.

Hope this will help

Dear Thanh-Canh Huynh,

Thank you for your response. Issue here is Flouqet Bloch Periodicity condition. The four vertical boundaries of my plate on which I am applying prescribed displacement as initial load, on same four vertical boundaries I need to apply Periodicity. When I did so, It does not work as, both conditions are on same boundary.

Reason for apply F-Bloch Periodicity is, I want to draw a dispersion curve.

Can you give an idea how can I do it, under the prepossessed condition, I need to apply F-Bloch BC.

Thank you

Dear Muhammad

As a matter of a fact for general cases, you can use the results of a study, say Study 1, as an input for Study 2. Lets assume you have 2 physics: Physics 1 and Physics 2. The method is as follow:

-In Study 1, untick calculations for Physics 2 and leave the rest.

-In Study 2 whose input data should be read from Study 1, you should untick Study 1, then in "Values for dependent variables" , look for "Values of variables not solved for".

-Set the settings to "User controll".

-Set "Method" to "Solution".

-Set "Study" to previous study whose data you want to use as input in the current study.

I hope that works.

Best regards
