It was about designing an excavator bucket.Ĭases like this one often require a computationally expensive Discrete Element Method (DEM) to model the bulk flow of different types of rocks or soil that interact with the moving bucket. While we were waiting to talk to somebody from the clinic on our alternative options, I thought about the power of choices and of one of the simulation models I had recently been working on.
And while it did not look so promising on the COVID test side at that moment, I realized how great it is to have choices in the engineering simulation world. And no doubt, placing your bet on a method in the trade-off between speed and accuracy is never easy.īut in the first place, what you need is to be given that choice at all. A smart simulation engineer gets to the solutions with the least possible amount of investment, I thought. Not just for covid tests, there is a constant trade-off between those attributes. Accuracy and safety, on the one hand, speed and agility on the other. The situation made me think about engineering reality. Who has the choice, has the agony! Or the chance? Given the tight schedule, it was our first choice as we headed into the clinic.īut then we found out that authorities would not accept these tests for crossing the border… We knew the rapid antigen test takes only fifteen minutes to get results. She barely stopped talking about how she was looking forward to it. For weeks she had been visibly excited to finally go back to university in person. She was about to attend her last year of her studies at a Canadian university.
I was at the local clinic, helping my daughter take a COVID test required for traveling across the US-Canada border. It was immediately clear, speed was the main factor to consider and we needed to get this sorted immediately. There were only three days left until the departure and two of these days fell on Labor Day weekend.
