COMSOL - Construction of micro resistance beam model - final temperature distribution and deformation - establishment of geometric model

 

 COMSOL Each of the Basic module

 comsol workflow

Multiple physical fields ： electric + heat + structure  

  newly build Model Wizard -- Analysis space

  Look at the characteristics of your model , Can be simplified -- In this case, we choose 3 dimension

Choice of spatial dimension

Selection of physical field  

  Built in physical field interface

Try adding an interface （ The interface is a prefabricated yard inside ）

  We can build one field by one （ Coupling of fields ）

 

  Choice of research type

The excitation applied is steady 、 Transient 、 Oblique

The result of post-processing to be obtained （ The process of timing transformation , Or the final stable process ）

  In this case, steady state （ Does not change over time ）

  Click finish + no ===》 Arrive at the final interface

How to add comsol The window of . Form message log

Then according to the model developer , To start modeling

The geometric -- Step 1 work plane  

 

  First draw the cuboid ：

Select the rectangle ：

Select extrusion in geometry  

 

  Realization effect ： lift

Build the inner cylinder

I'm in trouble You should use the inner cylinder directly But in order not to let their work in vain -- Just be the review in front

 

Subtraction

The stretching effect  

---

Build the box inside

---

Build a triangle etc. Finally, according to the operation
