Convergence of a Solution

The Solution of a Differential Equation or a Set of Differential Equations Converges vers the Exact if it is Consistant and it is Stable : Lax's Theorem. Since the Exact is not always known it is convenient to apply this Theorem. Numerical instabilities are a result of Roundoff errors and Truncation errors. The Domain of Stability can be obtained from a Von Newman analysis in the Complex domain. This implies a condition (relation) between the variation steps.

Dear All,

I am trying to simulate a milling operation with temperature. This is a 3-D simulation. I am using C3D8T element type. It has 1,2,3 and 11 degree of freedom. Can you please help me in choosing an other solid element type which has additional 4,5 and 6 degree of freedom. Therefore, I need a solid element type with 1,2,3,4,5,6 and 11 degree of freedome. I get this warning: ***WARNING: DEGREE OF FREEDOM 4 IS NOT ACTIVE ON NODE 14 INSTANCE WORK-1 -

THIS BOUNDARY CONDITION IS IGNORED

Thanks

Forced vibration

modal dynamics

Here is how I have carried out the forced vibration
simulation. After an “intial step”, I chose “Linear Perturbation” to first
extract the natural frequency. My next step was “Modal Dynamics”. I then
applied the load in the form of a sine wave under the same step. I have an
isotropic material. When I try to submit the job, I received following warning:
