1. ## Stiffness matrix

Hi, I extracted stiffness matrix using DMIG . How to identify the stiffness value of the node and direction and matrix size in .pch file? Pls refer the attached image for reference.
2. ## When should the temperature_flow stagger be used?

We typically suggest to use temperature_flow if the properties are strongly dependent on temperature. Treating flow and temperature as one large matrix can aid convergence in these cases. The degree to which it aids convergence will be extremely problem dependent, so it is difficult to make a blanket statement. If the free convection is dominant, temp-flow would have more effect than if the forced convection is dominant. If the flow equations don't depend on temperature, solving them separately will be faster.
3. ## Hypermath - index of a value

Dear all, Does anyone know how to get the index of a particular value from a matrix in Hypermath ? Regards, Beeyan
4. ## Stiffness calculation

Is it possible to calculate the Stiffness (N/m or N/mm) of the structure from any analysis??
