I have created as many steps as load positions. Since the deck I have modeled is built by shell elements, I have made "partitions" of the deck, creating surfaces where I will apply "surface loads". I am using a 3D model of the bridge, by combination of shell, beam and truss elements. Later, I will start using input files or scripts but first, I want to make sure that what I am doing is right. I am not really an expert, and you better ask someone who has more experience in this field. RE: Abaqus CAE extremely slow IceBreakerSours (Bioengineer) 26 Jul 12 14:19 are not very memory-demanding, the computer could be affected. I haven´t noticed any issues in other problems, but since Word, Excel, web browsers, etc. I am thinking if the problem may be in the computer itself. Rob: I have tried to "save as", changing the directory, changing the name of the CAE file, erasing different models I had in the same CAE file, changing the names of the models, etc. I have deleted most of the files Abaqus had created from previous works (I have reduced the file size to a 10%) but the problem remains. In this inactivity period, if I try to close Abaqus, suddenly the following message appears: "Unexpected Error 193", and Abaqus crashes. and when I click the OK button, this is when Abaqus takes 2-3 minutes to come back to activity.
I just want to modify some parameters such as load value, time period, etc. IBS: the problem is the CAE preprocessor. RE: Abaqus CAE extremely slow FFFMMMAAA (Civil/Environmental) Even in the older models, if I try to change any parameter, it still runs very slowly.
And this is the moment when Abaqus CAE starts running so slowly. It´s not maybe the fastest way but it´s quite intuitive.Īfter analyzing some results, I wanted to change the weight of the vehicle and consequently the value of the pressure load. Depending on the speed of the vehicle, I introduce different values of the time period. Moreover I am using ramped amplitudes (linear) to represent the approximation of the load, and dissipation of the load. I use surface loads, instead of concentrated loads, to avoid high acceleration problems. In order to model the moving load, I generate 81 steps: each one representing a certain position of the vehicle on the deck. An initial approximation I am doing is divide the whole deck in small surfaces: 1m long and width depending on the size of the vehicle wheel. I want to start analyzing the dynamic problems it may present due to a moving load (vehicle). I´ll explain my problem briefly: I have a 80-m-span deck.
