Applications for Simulation

Simulation can be used for many different purposes, and I wanted to describe a few of them in detail. I pay special attention to the ones I’ve actually worked with during my career. Note that these ideas inevitably overlap to … Continue reading

Architectural Considerations for Simulation

The simulations I’ve written, designed, specified, and utilized have incorporated a number of different features. I found it interesting that I was able to describe them in opposing pairs. Continuous vs. Discrete-Event I’ve gone into detail about continuous and discrete-event … Continue reading

Verification and Validation: Observations for Simulation and Business Analysis

Verification and validation are complex subjects on their own (and see here and here more specifically for this discussion), and the simplest way I’ve found to describe the difference between them is that verification tests whether a solution works while … Continue reading

Simulating Human Action

I used the book “Fundamentals of Classical Thermodynamics” by Van Wylen and Sonntag for my thermodynamics classes in college. In the first chapter it discussed the magnitude of relativistic effects compared to the magnitude of the general effects that would … Continue reading

Oakland/Berkeley/San Francisco

Today I stopped in to Berkeley and Oakland to see family. I didn’t actually see the Bay on this trip except a glimpse as I was coming over the hill towards upper Berkeley. I always love visiting, swing dancing, hitting … Continue reading

Prettying Up the 3D Graph Output

Here I’ve prettied the graph up so the lines change color every 100 degrees F, and I’ve added a legend. I suppose I could choose consecutive colors with a bit more contrast.

Graphing the Matrix Output

Here I continually run the heating routine for a piece with an initial temperature of 70 degrees in a furnace set to 2300 degrees. The temperature scale, expressed vertically, runs from 0-2500 degrees. The bottom of the piece, which sits … Continue reading

How Quickly Can the Matrix Be Solved?

The solution was finally made to run last week. Today the question is how fast the thing runs. My feel for the answer to this question has to do with the context in which I first asked it. From 1994 … Continue reading

Static and Dynamic Coefficients in Matrix Thermal Solutions

Recalling yesterday’s initial heat balance equation for each node: it should be noted that the values of both the specific heat and the thermal conductivity of steel are themselves functions of temperature. That means that these values need to be … Continue reading

Reverse Engineering Or… What Was It I Was Trying To Do There?

While continuing the process of turning the JavaScript graph widget into an object I found I needed to create labels of various kinds, which you see added in the examples below. I also wanted to test out some more of … Continue reading
