Some of the replies in the thread are clear that it will not be possible to build an analog computer that can solve the concerned problem, while the others worry about the complexity, cost, reliability, risk (probability of success), future use, possibility of not being able to come up with an...
These systems (e.g., particle systems) are usually used in computer games and the accuracy offered by them is poor. It is okay to use them for gaming since there it is enough if the simulations "look" realistic. They are usually a very crude approximation of the true physics. They are not...
But the problem definition does not specify how the input varies within 30 milliseconds (input is constant). Once the problem is clearly defined, that definition of the problem would be the true physics (although the reality can be slightly different). Anyway, the very final result is the image...
To avoid confusion, let us not use the word "frame" when it comes to analog computing. All I am interested in is to get the solution within 30 milliseconds. The steps that you have mentioned may refer to how the input is applied. I am interested only in the final value of the input (or the final...
Even if the analog storing is more expensive and less flexible, if it could be faster then still one could think of them (of course, I have taken note of the concerns raised in several of the replies, over the use of analog computers). Of course I would prefer a digital computer (can try RISC...
I need the concept of frames because the biological organ is displayed on a monitor which is connected to a digital computer (the analog computer is coupled to that digital computer). In analog computers, I think the "frame rate" is limited by the settling time (time required to change the...
Still people keep looking for better solutions. Otherwise digital computers would not have come into existence, if people were satisfied with analog computers (and did not try for a better system).
In an analog computer (for our problem), if input is constant output will also be constant (after the elapse of the settling time). The input can be changed thirty times per second (or, every 30 milliseconds) so that the output will also change the same number of times. This itself is the frame...
It is enough if the organ is divided into about 1000 elements. That is why I told in one of my earlier replies that we could aim to solve a set of 5000 equations. These numbers (total number of equations in the set) are not just arbitrary numbers; I have arrived at these numbers by careful...
I was aware of this kind of simulations about ten years ago. This kind of simulation (using spring-mass systems) is decades old. I am not happy with the method (hence looking for better methods. "I am not happy" in the last sentence is not just a subjective opinion of just one person (me) but it...
Could this mean that one cannot design an analog computer that can solve this type of a problem (it is not just a prepared-for switching problem, things will change during the simulation, variability of the problem)?
The literature clearly tells that building surgical simulators (used to train surgeons in surgical procedures) is much much harder than building flight simulators (used for training pilots).
These are already tried in the literature. Again, these are some of the other ways of getting some approximate solution.
One more approximation that one can usually come across in the literature is to compute -- instead of thirty frames per second -- much lesser number of frames per second and...
