While the main worksho p will be held 9th to 11th of June\, an excursion to Forsmark\, the Swedis h deep geological repository site in crystalline fractured rock\, is sched uled for 12th of June. The excursion is optional and\, like the workshop\, free of cost. However\, spaces for the excursion are limited\, so please sign up early to secure your spot.\nObjectives\nThe workshop brings togeth er experts in discrete fracture network (DFN) modelling to explore and dis cuss free and open-source software solutions for nuclear waste repositorie s in fractured rock. The software to be demonstrated will include OpenGeoS ys and porepy\, and the number of software will continue to be updated her e as registration starts. The objectives are to:\n\nShowcase and criticall y evaluate existing open-source software tools through presentations and h ands-on demos/hackathons\nFoster exchange and collaboration on DFN-modelli ng approaches and challenges across geological settings\nDevelop recommend ations for modelling approaches in nuclear waste disposal\n\nPreliminary s tructure\n\nDay One: Expert presentations from participants addressing cur rent challenges and advancements in DFN modelling (10:00 - 17:00)\nDay Two : Hands-on demos/hackathon sessions of free and open-source software to le arn about functionalities and possible use cases (10:00 - 17:00)\nDay Thre e: Presentations and demos alongside gathering of collective recommendatio ns for future research collaboration and modelling considerations for nucl ear waste disposal (10:00 - 13:00)\nDay Four: Optional excursion to Forsma rk (08:00 - 16:00)\n\nLogistics & Costs\n\nParticipants are expected to co ver their own travel and accommodation costs. \nWe strongly encourage par ticipants to bring their own laptops to both present their own software/pr ojects and test software discussed during the workshop.\nSee https://www.u u.se/en/campus/angstrom-laboratory/visit-us for information about the venu e.\n\nPlatform notes\nBefore the workshop\, if you have submitted a presen tation contribution\, we would prefer if you uploaded presentation materia ls through the platform by creating an account at indico.global. Please no te the "Protected" field. It determines if you presentation is publicly av ailable to everyone\, only for participants or only for the organizers. Gu ideline to only show for participants: Toggle on "Protected"\, then click "Registrants" and choose the "Registrations for ..." option.\nFor those ho lding demos/hackathons\, we will contact you separately regarding how mate rials will be distributed to participants.\nThis site will continue to be actively updated until and after the workshop so please stay tuned. The ti metable of presentations and demos along with their titles and abstracts w ill be published at the latest shortly after the call for contributions/ab stracts has ended mid April.\nPlease do not hesitate to contact us about t he workshop\, any issues or about this platform! See contact emails on the left.\n\nhttps://indico.global/event/17157/ LOCATION:2003 Lärosal (Sweden\, Uppsala Universitet\, Ångströmlaborator iet) URL:https://indico.global/event/17157/ END:VEVENT END:VCALENDAR
